Okay here is my one & only "jack-ass stunt". This one won't get you into the bonnie speed record books, but it has the potential to get you a Darwin Award real ez if something goes bad.
One Sat. morning last spring, I was talked into drafting a friend, on my 76 PUCH w/70cckit, behind his 10 wheeler dump truck. Everything went fine for a while (he says we were doing better than 60 mph, my speedo was long ago pegged out at 40 mph) when we passed a group of Harley "RUB's" out for their AM cruze. I was so scared I couldn't pay attention to see the look on their faces, but another friend who was riding along in the cab said they all had their mouths wide open. I really got scared after that and backed off the throttle!! I'm sure the ped would have done more. But sanity and stupidity do have their limits.
