Cool....I remember back in the 60's they had a race here in town on a pretty wild downhill. The local GM dealer sponsored it. The guy at the dealer showing me the blueprints on how to build one.

Remember as poor kids building our own. Taking wood from the dump....and stealing wheels off shopping carts at the local food store. The following year the store had the wheels riveted on. But I'll never forget the "course" we used....real narrow, steep downhill with steel wall sides. This one kid plowed that wall head on....mashed that "car" in half. Love to have a video of that to watch it in slow motion...LOL.
