@edgarblythe,
All this activity has caused me to start taking better care of my yard. I had let the back revert to forest growth, to make it inhospitable to the folks living in the heighborhood behind us. For a time, every day when I got home, kids from there would be in the yard. They were tearing down my new fence. Then I came home after telling them and their father I didn't want them there, and the father was back there too. I put a big Keep Out sign on a tree by the fence line and then let everything grow over. Even I feared to go there the last two years. Now, I have it about half cleared, and do a little most every day.
