Like my dad always said "some people are born stupid and others work hard at it." Not sure which this guy was but he was definitely STUPID. And even a crossing gate to the face can't fix stupid. But it sure as hell stopped it!!!!
If he had a proper motorcycle that you can sit on and look forward he probably would have seen the sign. I think the problem is when you're laid out on a crotch rocket you're looking down at the ground in front of the front tire, he probably couldn't have seen the arm coming down even if he wanted to.
+1 for a harley, a proper bike. -1 for a crotch rocket
Stupid fella, tricks are for kids. Hate to hear it, but you gotta try to prevent the easy stuff from happening to you. Hope he learned a valuable lesson and will be ok.
