in their defense, I have been riding for 40+ years and I think I can handle a bike as well as most folks. I always got a kick out of doing 180's on a narrow country road w/o getting off the pavement. I always like to try to balance the bike at stops w/o putting a foot down.
2 months ago I bought a Kawasaki Nomad 1600. I find it is much more difficult to ride at low speed than anything else I have ever had. This is the first cruiser I have owned in the last 20 years. These big fat pigs are just harder to ride at parking lot speeds.
If that isn't enough, I find a lot of people riding cruisers are very inexperienced.
I have done a few pgr rides, but haven't done any in the last couple of years. I do remember some of the guys seemed to want to "play army". It didn't bother me.
