Almighty then thanks picklz. Here's the list I can think of.
Burgers/brats/hot dogs.
^ buns.
Chips/sides.
Drinks - soda/water.
condiments - ketchup/mustard/pickles etc.
Grill,charcoal,lighter fluid.
That's everything I can think of. If you think of anything else lemme know. We probably need enough for about 20+ people, so if some people want to tag team some stuff go for it! I'll also put this list on the first post as well.
