I think I paid $80 to sit in the lower tier seats between the flagstand and turn 1 at Darlington four months ago. Oddly enough I noticed gaps in the crowd upstairs so I just wandered up there and no one checked my ticket. I could have sat up there all night if I wanted to. Free and (relatively) close parking was plentiful on site and they let people park there overnight to miss the traffic jam and leave in the morning which is what I did. Id think twice about going to Daytona though. I shudder to think what they charge to park within walking distance now.
