I was nervous about putting them in my yard also, having battled with 2 of my neighbors over the years. I have a 6 foot block wall around the place (fort golfpsycho), but still felt I had to hide them. They are near a garage, and a tree obstructs part of their flight path. In watching them, for the most part, they go pretty high pretty fast, and I got no complaints. When I passed out the bottled honey a few weeks ago, all I got was smiles, so I am emboldened to expand a bit, and move them into a shaded, but more visible area in the spring.
