Rick, by the looks of your area radar accumes, you won't be needing roof water for a while. Can't buy a drop here.
Here's a picture of our little buddy living in a flower pot on the patio deck. We typically see him in late eveningtime nearly every day. We discovered his nest around the fourth of July when I turned the water hose on this pot, he came flying out about 2 feet high. I took this picture last night just as darkness was approaching and he was emerging from his hole. It is poor quality but you can see him directly in the center. He made it plain he didn't like the camera and became very vocal and yappy about it. Otherwise, he seems to enjoy our presence and company, quite a bit in fact.
