I just learned several things watching this video:
1. If tube buggies are badass, welding more (useless) tubing makes things extra badass.
2. If you have all that extra tube and have aforementioned "extra badass buggy", YOU are equally EXTRA badass and don't need a helmet to protect your noggin.
3. If a sport includes horsepower, a hill and an open exhaust - you will attract lots of people.
4. God is involved, since nobody was killed.
I hate noise, but the noise those things make sure is purty.
