Train your kids the noble art of polar peeing (and the other business) before you need it. Nothing particular mysterious about it, just go hiking and camping and the training presents itself. But invest 2 minutes with your spouse discussing the proper technique for "draining" the kid before the need actually is there. My wife's first attempt at our boy was hilarious to watch. (Ladies- the thing goes out the front. Although anatomically possible the other way around is rather awkward).

I have the deepest respect for my wife and lady friends, who resolve these issues the old fashion way. I've done "big business" in a friggin' blizzard at Spitsbergen and it was not something for the faint at heart. In more moderate conditions I just enjoy the scenery.

I've seen these gadgets before, and people seem quite happy about them. I am sure these little gadgets can provide huge leaps in comfort for our lady friends, particular in a semi-populated setting where modesty and non-existent restrooms are not the best combination.
