Figured I throw this story up on the board Three months ago I was attempting to go from Fort Collins to the Berthoud MX track on my F800GS to play around. I've never been there before but I knew it was located off I25. My buddy wanted to bring his mx bikes and meet there at 1600 on Friday. I got to I25 and traffic was gridlocked. I frustratedly exited at Loveland and figured I'd just take some sort of frontage roads. After exiting I25 I immediately got stuck behind a black nissan altima. The altima was driving erratically and slow. At this point it didn't matter because there was nothing I could do so I stayed behind him. Then I seen the frontage road that I thought I was supposed to turn onto. It was a one lane left turn at a stop light. The altima was also making the same left and was still in front of me. There were 20 cars trying to make this left turn and only 4-5 were making it through the light at a time. The 10-15 minutes I sat in line at the light I noticed that the altima wouldn't move forward at times, and somehow managed to almost go completely out of his lane while we were inch'ing forward. It was apparent the driver was doing something besides paying attention. Eventually there was one car, the altima, and myself inline for the next green turn arrow. When the light turned green the altima sped up started turning left but went wayyy wide, out of the turning lane, started to go off the shoulder, and off the road completely...at this time I noticed that there was no oncoming traffic, so I gas'ed it over the double yellows sped up, passed the altima and the car in front of him, and looked back to see the altima drift back onto the road and back into his initial spot. Now I'm like, "dafuq just happened??" But I now have some space in-between the guy behind me and myself. I continue on and watch my mirror noticing that the altima is riding the ass of the car separating us, and the altima is weaving in and out of his and the oncoming traffics lane. I eventually come to a roundabout, and though I was now lost, I decided to head south. I check my mirror and see that the altima continues west still all over the car infront of it. Half a mile down this road I decide to pull off on the shoulder to check my phone gps and see where I was. The road wasn't populated, few farms here and there, and I was sitting on my running motorcycle with my earphones in listening to music. As I'm looking down at my phone I get a knock on my helmet. I look over and see a guy 5'11", around his 40's, big mustache, white trash nascar shirt and hat, beer belly that protruded to the extent of his arms, and cowboy boots. This guy is yelling at me, but I can't hear anything. I thought he might have been one of the farmers seeing if I needed help. I give him the hold on finger and look down at my phone to turn off the music. After I turn it off I look up and notice a black altima parked 20-30 yards ahead of me on the shoulder. Now I look at the guy and he's yelling at me about being dangerous. Since I'm not tall and barely balancing the gs between myself, and had no intention to start an altercation, I shoved my phone in my tank bag, put my bike in gear, told him to go f off, and I got out of there. End of Story, right? NO! I look back and see this guy running towards his car. I'm completely lost but gas it to 60mph and look back to see him catching up to me in his car. I give it more gas and see a T stop sign ahead. I slow down, but don't stop, and watch him in my mirror blow the stop sign as well. Now he's catching up again so I see a right hand turn. At 60mph I brake hard, downshift, and make the turn. He's going so fast that he loses control of the car and slides past the turn. At this point I realize this guy is psychotic and is capable to doing grave harm. This chase continues at speeds of 110mph and for a couple more miles and turns. Finally I make a turn and see I25 ahead. I figured I'd get on I25 and do what I needed to to put some space in-between us until I could find a safe place to call the authorities. Just as I'm about to reach I25 I noticed I passed a big gas station. I decide to bust a U-turn into on-comming traffic to get to the gas station, because I knew there were cameras and witnesses there. As I'm heading towards the entrance of the gas station he drives into the oncoming lane heading right towards me and cuts me off at the driveway to the station. I go around him and b-line the doors. I jump off my bike and watch him fly into a space near the pumps. I decide I'm going to run inside, tell them to call 911, and attempt to find a place to wait until the police arrive...but as I see him get out of his car and start running at me, I look over and notice a State Trooper getting gas!!! So I yell at the trooper and start running towards him. The guy looks over at who I'm yelling at and awkwardly stops running and walks into the gas station. So I talk to the trooper and update him on everything that went on. We talk for a few minutes and discuss my options. Then he ask me, "is that the guy," while he points at the gas station, and sure as shit the guy is inside, hiding behind the cases of cola lining the window, with his head popped up, just starring at us. This guy has severe psychotic problems! I had no proof that anything happened, and I could take the guy to court, but it would be my word against his. At this point I don't have any desire to go to court so the trooper told me to take off and he'd make contact with the guy, run his info, and go from there. The End. Never, ever, ever would I have expected any of this to happen. My background is Law Enforcement, through the military, and through military contracts. I know my capabilities and I know how to handle situations. If I would have tried anything during the initial confrontation, the whole situation could have ended badly, for me, or for the other guy. A lot of people say that if they were in my shoes the would have (hit, fought, shot, smashed, etc) the guy. - No you wouldn't have. I was balancing a running, brand new to me f800gs. All he would have had to do is push me over to gain an advantage. During the initial confrontation, I assessed the guy as crazy and wanting to yell. He didn't appear to want to start a physical fight. My decision to ride off was to de-escalte the situation and end the whole situation together. Maybe telling him to f-off was his breaking point. But the part that worries me the most is that the whole situation could have been a lot worse. He could have approached me and took a bat to my face, shot me, or just rammed his car into me while I was sitting on the shoulder looking at my phone and I would have never seen it coming. The reason I posted this story is due to the recent "motorcycle gang vs suv" thread. This guy attempted to enforce HIS law on me, the same way the gang attempted to enforce their law on the SUV. There are psychotic and deranged people out there, whether it be in NYC, or the beautiful front range of Loveland. Ride vigilantly friends.
