@utstnx what are you looking to do? I'll be there, don't have tickets yet. I'm still looking for 3 tickets at the price I'm willing to pay

There are plenty of people tailgating around the stadium. The weather and concrete can make it hotter than it should be. The weather has been pretty mild the last week or so, hoping it sticks around for another 2 weeks.
Some great BBQ in the greater DFW area (Hutchin's in Frisco & McKinney, Lockhart Smokehouse in Dallas & Plano, and Pecan Lodge in Dallas). There are tons of pretenders around the metroplex, some will have long lines - Pecan Lodge consistently rated one of the best in the state you could wait 30-60 mins depending on when you show up. Hutchin's has an all you can eat option for $20 (best value and their food is really good). If you go to a BBQ joint that I mentioned above, you won't need any bbq sauce.
Stockyards in Ft Worth, Six Flags/Hurricane Harbor in Arlington (near stadium), Dealey Plaza in Dallas,
As
@OldPlayer pointed out, Tide In Texas has an event at Gilley's Friday night (
Tide In Texas Events).
If you're wanting to get out and explore, there are some really cool towns around the area, but you're gonna have to drive to get there. Denton and McKinney both have really neat little downtown squares, Granbury also has a really nice square but it's a little further out.
Cowboys just opened their headquarters in Frisco, worth a visit if you're a Cowboys fan.
