I like to fly kites in the local park, and people seem to come from miles around to let their dogs crap on the grass. Most of them do clean it up, but that's not even sufficient when you've got hundreds of dogs crapping over every square foot. The whole park is just covered in poo and I've stopped going there. It's surreal to be there in the winter and see a line of cars wanting to do nothing but jump out, crap and drive away again.
I've got a neighbor with 3 big dogs , he stays home to take care of them while his wife works. He takes all 3 dogs to the park in his car at least 3 times per day. He never does much of anything else that I can see. Between the 3 of them, he must collect a pound of turd each time. I like dogs as much as the next guy but I just can't see the point in living like that.
I'm not trying to start some flame war, I like dogs as much as anybody, but it seems that we've got to rethink the way it's done, at least in the cities.
