Yay, some local history... Bigfoot's Hazelwood, MO location (just outside St. Louis) was just a few miles from my house. The birthplace of the "monster truck". They used to leave the first model parked out by the highway.
That sounds like it would be pretty cool to drive past! A local auto shop has a monster truck with smallish tractor tires parked out front, but that's pretty tame compared to these monsters.
