Similarly, when you're tearing down camp, pull down the tent first and pack up all your gear. THEN, put on your rain gear, and take down the tarp. I would've assumed everybody here would do that, but looking at the soggy pile of tents makes me wonder.
While I'm at it, the second thing, if not the first, is find a latrine area, throw up a ridge rope and tarp. Then you're golden. I shudder when I think of the many times, in the rain, in the middle of the night, nature called. Could be related to all the booze around the fire and junk food consumed. Nothing worse than being soaked with rain, 2 in the morning with soggy toilet paper. YMMV, of course
