Displaced Braves fan looking for some pointers

I’ll be making my first trip down to Houston with a buddy on Wednesday for the game and just wanted to know if y’all had some pointers.

Best parking for tailgating and anything we should hit up before the game?

We plan on getting there about 3 hrs before the gates open and are debating tailgating or checking out the city?

Good luck to y’all and I hope this goes to game 7!
