For the opener I like to get there at about 7:30am - on Saturday! Too bad our RV trip is getting pushed this year (stupid work / having to make a living).
OP, per everyone's advice, just find Hammer's Lot and hang with TBD! You might there there are just a bunch of Internet nerds on this board, but in real life we're a bunch of models, actors and scholars...
Also, watchout for the molemen and those tailgating too hard, they'll get ya!
