I'm only participating in planning since I'm probably not going. If I were going my planning would be:
1) Say "Yeah, we'll be there."
2) Several months later: "when was that trip again? This Saturday? Oh."
3) Night before: I should go buy some groceries...I"ll just get them on the way out of town.
4) Pack in the morning I depart just picking random camping stuff out of storage.
5) Have a blast even though I find out I forgot the sleeping bags, eating utensils, and clean socks.
To get you started here is
a Wiki for it with the above supply list (though if you're really going to take all that crap you might as well just stay home and have Safeway.com deliver some citronella candles).
