I like your approach. I just built and I have neighbors who are doing everything from that to other things. The neighbor who's dog is crapping in my yard (actually 2 big dogs) is a little complicated because I have trees that are knocking the fence out. I have been working ($$$) to remedy that, but there's still areas they could patch. Their dogs do a daily roam and I find some big piles from time to time (we have 2 pugs). I considered a sling device, maybe just get it into their yard, maybe aim for their deck, whattaya think?
