Far as entertainment value is concerned it's worth every penny of $10. I'm well aware that purists and Body fabricators don't like it. Name another short track that gets 17,000 butts in the seats every week.
The drama (and drama queens) is what fills the stands today. Back in the late 1980s the stands were 80% empty. Train races, can't pass without wrecking somebody, drivers refusing to obey track officials, fights in the pits, fights in the stands. It was a mess. Meanwhile the other tracks in the area were pulling good fields of cars and great numbers of fans.
Not sure if they changed promoters or not, but the current promoter pumps the drama. Still have train races, can't pass without wrecking somebody, drivers refusing to obey track officials, fights in the pits, fights in the stands - but they're appealing to fans who like to see blood. They even promote driver rivalries like they are prize fight bouts. Plus, unlike other tracks, they advertise.
Around the same time some of the other tracks fell off due to poor management decisions and changes, and an unofficial area dirt track circuit (Oak Level or Ace on Friday, 311 or Friendship on Saturday, and Wilson on Sunday) fell apart. Oak Level closed / reopened / closed again, Ace and Friendship got paved (Friendship temporarily), and Wilson closed. That caused dirt teams and fans to look elsewhere, which helped Bowman-Gray. The Southern Modified Tour (which has changed names a few times) also bolstered the modifieds because it extended their season (B-G starts late and ends early). Caraway got NASCAR sanctioned, which generated higher fees and car costs - and also diverted some teams and fans to B-G.
B-G is one of those thrills that you should try once... then decide if that is enough. You can sit low in the stands and feel cars whiz by just a few feet away. Admission is $12 (adults) and the concessions are pretty good and reasonably priced. You can actually buy a professionally printed program. The facility is well maintained. Most of the teams hang out with fans in the pits after the races, and B-G doesn't turn the lights out minutes after the racing is over. If you have kids you might not want to sit along the front stretch - that's where most of the rowdies sit. Most of the time whomever on the front row manages to get through turns 1 and 2 first on the first lap will lead the whole race. Typically it's follow-the-leader after two or three laps. You will see cars intentionally take other cars out. About a 50% chance that after a wreck a driver will exit his car and try to fight another driver - on the track. The Madhouse show televised it all... the new show not so much (so far).
