I'm of two minds about this... first being I understand the need to go when they have to go. I probably would have done the same thing. But at the same time, I was on the opposite end of the coin just this weekend. We were having a picnic under the shade of one tree when a little girl just run up to the tree across from us, pulled down her pants and went. It got me to thinking aside from dog pee and all that, what else could we possibly be sitting on. And of course, my kids are playing in the grass just rolling on the ground all over the place, right? It honestly grossed me out. So I don't know. I completely empathize with your situation, too, though. So I guess I'm no help! LOL.
