Dad has some good stories about those, one that sticks in my mind: when he was racing the RMSHA circuit early on in its life, the circuit took them to a "hillclimb" back east. Was more like a dragrace up a slight incline. He and a bunch of racing buddies rolled into this place with their machines, unloaded for the test and tune day and the locals couldnt believe what they were seeing! LOL! Almost couldnt get and tuning done for the hoards of people around their sleds drooling. "where do you get a track that long!?" LOL! "how do you keep the front end down with those things bolted to the track!?". And the best comment that stuck with him was from one of the local competitors: "awe, crap. We're all gonna lose." hahaha!
Even better, he can tell you about the days they used aluminum angle for paddles...we still have a bunch of both in a box in the back of the old shop.
