I must admit to leaving it in some areas. The island (this wooded park area on a strip of land in the middle of the river) we go for walks on is a place I normally leave it. There are so many geese that there is crap everywhere you walk. Autumn used to only poop in our yard but I haven't enforced the "go before we leave" rule so she's usually goes on our walks. I pick it up everywhere else though. People have yelled at me to pick it up when she is obviously peeing. I hate that.
