The whole thing was awesome, but I mainly went for Bad Religion, and they were great. Greg joked around with the crowd a lot ("Of all the American things you could choose to emulate, why Texas??", upon seeing the number of cowboy hats in the audience) and the music was great. Lots of people singing along, and a great selection of songs. They pulled in a huge crowd, and I noticed that there were more people watching them set up than were watching the other band who was playing at the time.
All in all, a great show. I'll be returning next year.
