A little off topic, but maybe you guys can settle the score. My apologies in advance for the potential grossness discussed.
On a recent multi-day bicycle trip through the boonies with little access to regular toilets during the day...which approach do you think is grosser (for a woman, let's say)? Go behind a tree, drop your padded bike shorts, do your thing, put shorts back on, then continue riding (note no dirty hands). OR...enter a disgusting porta-potty with questionable cleaning history, do your thing, use the cheap toilet paper, have no way to wash your hands, then go on your merry way?
I won't say which side of the argument I was on...
