I carry a 5gal bucket w/tp and several plastic grocery bags for any #2 duties, and a plastic urinal bottle for any "pee breaks".

I probably still have one of the folding potty stands ... shoved away someplace. But it took up too much room in the boat, so I just tucked it away and opted for the 5gal bucket (since I always carry it on the boat, anyway, because I transport electronics & other things in it).

I suggest the 5gal bucket & a non-clear poncho be used for female anglers ... as opposed to putting them out on the bank or mad dashing back to the marina or launch ramp porta-potties (if they even have them).
