Mike, we had a problem with a possible stalker/disgruntled client earlier this year. My house backs up to a wooded lot. I found a remote security light that operates on solar power at The Home Depot and I put a few of them up in the trees ( I had to mount the solar panels on a galvanized pole and raise them above the tree canopy). It inconveniences the wildlife a little, but it has kept people out of the woods. It's like an episode of
The Fugitive if anyone walks back there, lights popping on as they dart through! It's pretty amusing!
