I would have kept pissin away!!
I was fishing the Nisqually this last fall and there was a couple kids about 30-35 yards upriver from me, basically kickin back drinkin beer more that fishing. Pretty soon I look up and one of them is glancing down at me, I then notice the other one pissin in the river. The one glancin at me starts giggling. They packed there stuff up and left.
I figure what little he pissed mixed in with that river worked out to be parts per billion by the time it washed down to me.
I wasn't catching anything, the only water I was coming in contact with was off my line. Oh no, I may have gotten one molecule of his piss on me

I've heard Dr Drew on Loveline mention that urine IS sterile. Did a quick search on the web and it does appear to be sterile. Couple sites claimed it was purer than distilled water. Now if exposed to air for a time, airborne bacteria grows on it.

I'd rather rinse my hands off in a river that was pissed in by a couple guys than some of the meatholes with all the stinky fish guts.
