Never seen 'em, but did remind me of the first time my crazy ass uncle got me up on skis on the Ohio river. I musta been about 10 or so, and once I got up finally he decided to see how fast and crazy he needed to go to knock me off!. He had an old Sidewinder at the time, 455 Olds if memory serves me right, and wasn't fast at all by our standards, but blistering to a 10 year old.
Didn't take long, and I like an idiot, listened to him telling me "You almost had it that time, try this and this, and I'll try and slow down a bit". Fell for that sheit 6 times! He still tells that story to his grandkids. Somewhere is an 8mm film of the events from my horrified mother on the dock, lol.
He did nearly the same thing to me after I moved out here and he had his Blown Biesemeyer, I was 30 something at the time then. yup, he got me again and again at Saguaro Lake. The phucker is a talker!
