I have to say.......urine is actually very sterile, unless you have some type of bacterial infection (ewww).
My DHs' friends used to pee in our pool all the time (bigger ewww), I realized this when vast quantites of beer were being drunk, but not one person had gotten out to use the bathroom.
When I gave them all he11 for it, their justifcation, was that the UV/chlorine would kill any germs it might contain.
Finally, they stopped going in the pool but started to 'go' on my bushes around the pool instead =[
So if their are any ladies reading this........it is like the saying goes, 'you can dress them up, but you can't take them out'.
What a bunch of boneheads!
