I felt this deserved a seperate thread. FYI to noobs on the board or people who have never been to TC before. Many people show up with extra tickets, and if no on in the parking lot needs them, drop them off with the ticket takers at the gate.
If you end up unable to get any tickets, I would just show up the day you want to go and see if there are extras floating around. If not in the parking lot, ask the ushers at the front gate.
This is a little known secret.
