Well, this is my Friday to work, and dont leave till 10pm. I get every other Friday off, so I'll see about next Friday. But, in general the parking lot starts to fill up around 6:30ish or 7:00 and can get really packed. About three weeks ago, I went by and there must have been over 100 cars there. Most stay till around 9:00. The people that own Biff's Burgers own a good size portion of the parking lot, and have about 4 or 5 main rows of parking roped off to minimize traffic where the cars are parked. So, I think it is a well organized place for muscle cars enthusiasts to hang and show their rides. So, see ya around.
