I am sorry I won't be there, sounds like a lot of fun.
Here's a tip, To do hot food for a lot of people we use to tell everyone to bring a can of Chile. Any kind, make whatever. Toss em all in a big pot, cut up some hot dogs and toss em with the Chile and wam you have Chile ala hot dog. Some bowls and spoons your all set. Add cheese and onions even better. The way the weather has been these days I might just make some up this afternoon. Of course someone will need to supply the dogs. And don't forget the paper towels
Have fun and a great time shooting
