tresj: Now this is how it's done! As dog owners ourselves, it's annoying for us too to find the 'stuff' in our parks, pathways and own front yard.
It's always a head scratcher when you see it, thinking, "how could someone just leave that there?"; and yet, admittedly, there's the times we forget bags and don't feel much inclined to go up to someone's house to ask for one.
To give the benefit of the doubt, maybe that's why we see piles at all. Hmmm...
Nevertheless, would like to take the opportunity to thank those kind people who attach a stash of bags to their fences for those 'uh-oh' times!
