We've found that a small Bloody Mary bar is quite nice on our annual spring, base camp/fishing trip on the S. Kawishiwi River.  Just the essentials though-1.75 of vodka, 2 jugs of Famous Dave's blazing inferno mix, asst. pickled stuff (asparagus, green beans, peppers and pickles), sharp cheddar, venison snausage, dijon mustard, worchestershire and a bit of onion and garlic salt.  Ice would really top things off nicely, but we prefer to keep to our minimalist approach, and leave the non-essential pleasantries at home.
