[svandamme]

it's water, with some ammonia in it... some people actually use that exact combination to clean things...

gull's,pigeon's, cat's and dogs piss on any spot you can lay your eyes on

as long as one tries to keep it somewhat decent(exposure, repetitious group use of specific areas), what's the big deal?
seriously, man has been pissing everywhere for thousands of years, and only recently have we become overly sensitive of it...

It's not like we are talking dookie's here
those, i agree, require proper disposal, and those do carry all sorts of bad bacteria and whatnot...
but piss, is just sterile water with some ammonia in it...it's not the end of the world
