This is the first I’m hearing about it, lol;
For years in the 1960s and early ’70s, Watkins Glen was home to the most infamous piece of real estate in racing, a mud bowl outside the track known as The Bog. Denizens of The Bog, known as Bogladytes, would drag old vehicles to The Bog, throw rocks at them and then set them on fire.

I spoke to someone recently, maybe even at Watkins Glen vintage, who was there. Someone I know, I just can’t remember who. Supposedly the bus wasn’t even theirs, it was just a bus greyhound or whomever had used to transport people to the track. Someone stole it from a different part of the infield and drove it to the bog
