What constitutes proper dog walking?

I've owned a number of German Shepards over the years, so I have no problem with dogs. But those big babies never RV'ed with us. We're currently in a very nice RV resort with grass between each site. First thing I noticed when we pulled in was the circular dead spots of grass similar to what I used to see associated with our female dogs urine. Just where I want to be sitting on a chair. Watching the seemingly unending parade of little doggies and their owner's I've decided that the grass between sites along the road is actually the dog walk area. Does anyone really think those little bags that the feces are picked up with gets it all? To me it boils down to this. The convenience of the dog and walker versus consideration of the person whose site your dog is using as a bathroom.
