Just do the park and ride and walk over to the Blue Crew. It's free and not a big hassle at all.
The Blue Crew are always acommodating so if you bring some beer there is always room in someone's cooler, if you bring something to grill there is always an open grill.
Just exit Fannin off of 610 turn right on Fannin, take your first left on Belfort Street, the first left is the station entrance, park (free), hop on the train (free). It will drop you off on the Fannin side of the Dome. You just have to walk across the Dome parking lot towards Kirby. The Blue Crew tailgate is on the corner of Kirby and the Blue/Platinum Lot.
This is exactly what I am doing. I will be there around 9am. I look forward to meeting you if you come over.
