I am bringing the kids (5, 7, & 9), it has become our tradition and they talk about it all year. Lots of stuff to stay warm (propane heater, 2 k-1 heaters, and a generator with a space heater to go inside the larger tent. Two tents (smaller for sleeping goes inside the larger), air matress, chairs, Thanksgiving dinner, plenty of snacks, Boy scout popcorn (for the hungry who came unprepared... helps our local troup and feeds the crowd, plus I get a letter from BB saying it is OK in case the police decide to give me a hard time), hand warmers, and my wife and the baby will be on stand by 2 miles away and will swoop in to pack everything up before the doors open.
I am also concidering the PP idea. Thinking about trying to get some local sponcers so no one will have to pay.
