Are you going to be there all 4 days? I'm not sure if I'm going Sat or Sun, but I'll be sure to stop by and say hi. Are you going to have shirts for sale?
I've heard as early as 5, but it usually doesn't get jumping until like 7 or so. There is a ton of parking, but the spots right by the restaurant fill up quickly and you usually get blocked in. I'm planning on rolling in between 530-600 or so. Just got done cleaning the ol' gal up. I'll be in the silver 04' Terminator vert.
