T.K.
Take Texas to 'em!
If you drive all the way from Texas and don't take a little bbq or Tex Mex you are doing those folks a disservice!
How about a good old fashioned bbq? You can get a couple of big briskets. Season with dry rub and take in a cooler. Have the men smoke them overnight for you. Then chop it up to make chopt brisket sandwhiches. Brisket, sauce, and buns. You can throw some whole cut up chickens on the grill too.
Take a couple mondo vats of potato salad and macaroni salad. A huge pot of beans cooked over the campfire and for desert - definately smore's.
