So many suggestions....... Something unusual and a good OMG factor is you cook it ahead. Stuffed potatoes.
Bake large potatoes, really large potatoes if you can find them. Sam's usually has 'em. Just wash, pierce them, oil 'em and roll 'em in foil. Wife can bake potatoes.
Weeks and months before start stocking the freezer with cooked sliced brisquet, sliced pork, turkey, and chicken meat.
Warm all that evening, warm your favorite sauce, have a place with the potato 'fixin's, butter, sour cream, green onions, caramelized onions, bacon bits, etc.......
You get a potatoe, fit it how you like, then you get the meat of your choice with sauce on top. I have seen this done for large and small parties and as long as the potatoes are cooked properly its always a HUGE sucess. Throw out either slaw and a roll and its a campfire cook out!
Bunches of stuff to do. Alabama, you could hang a big pot of brunswick stew or venison stew. And bisquits!
I am sure whatever you do after an all day ride, they'll appreciate it.
