Took a ride on my 88 K75 today to get my hair cut, what there is of it. I'm on Cave Creek Rd. heading south for those of you who know the phoenix area. I'm doing 50 or so in a 45, watching my mirrors and getting ready to turn West on Thunderbird. Suddenly, a guy screams by me doing at least 80. (I saw him coming). He was in his lane, the one left of me, wearing helmet, shorts and T shirt. As I'm watching him, I'm startled by his buddy, I assume, because his exhaust is a lot louder. He's doing maybe 85-90. As I continue on, thinking WTF, I see them both pull into a strip mall type area and park their bikes...walking into a store. Now this stretch of road is very busy, lots of shops, side streets, stop lights, etc. Not a place to be doing that kind of speed. Don't get me wrong, I like speed. I love sitting at 90-100 mph. in the right circumstances but I just don't get what these guys are thinking.....or not thinking. They were young, I'm guessing teens to mid 20s. Where the hell did they get the idea that it's OK to do that and where did they get the idea that they can't die? Even in my wildest days around that age, I never did anything that stupid.
