Louie I would seriously consider "stealth" parking the night before the game. South of the stadium is more industrial. North is the big Texas Medical Center, and north of that is the central business district. Due east of NRG are a lot of apartments. That would be my first choice. Anywhere that doesn't have a "No Parking" sign will work. I wouldn't be running a generator all night in front of someones house though. Stealth....no lights, no gen, steps up, etc. I would have a chain to slip through the spokes of the front wheel and suspension to maybe prevent a tow while you're away.
Train system runs basically north and south from the stadium area to central business district.
It will be a mess. Good luck. Let us know.
