At least year's Warped Tour, the bands started playing while I was still in line. On the "main stage" was For Today, and I listened to about 10 - 15 minutes of them while waiting in line and walking to where all the other stages were. From the second I actually got into the amphitheater to the time I walked through the "village", down a big-ass hill and up to the parking lot where the other stages were, all For Today did was preach. Ugh.
