Diki, all you need for a bar at an outdoor, powerless event, is a couple cooler chests filled with ice cubes and someone to serve the beverages, which are usually plentiful. As for lighting, bon fires usually supply all the light needed for nighttime events, such as those held at campgrounds. I did an indoor, powerless job at a hunting camp in the Pennsylvania mountains, where the lighting was supplied by kerosene lanterns. The lodge was huge, probably about 10,000 square feet, massive fireplace for heat and a wood stove for cooking. As for catering, I guess you have never been to a tailgate party. The hosts usually tow a big BBQ smoker behind their cars or trucks, and the food is fantastic to say the very least. No electrical power at any of these locations, but they sure have lots of parties, music and fun.

Good luck,

Gary
