My wife and I are flying down to Houston on Saturday, hanging with family on Saturday night, and then going to the game on Sunday. We've got our tickets but we didn't get any parking passes or anything like that. What's the parking like around the stadium? Do we pay on the way in or should we buy something in advance (if we can)? And if we do, what's the best to buy? Easiest to get in and out, etc. BTW, I'll be the guy in the #55 jersey with Pencilneck on the back.
