I live in the back part of a duplex. It is surrounded by a u-shaped backyard and enclosed with a tall wooden privacy fence. I have a large seagrape tree with branches that hang over my bedroom roof, which is in the back. I live alone and last week there were crazy noises on the roof, scraping, rolling. We have raccoons, possums, squirrels and I thought that's what was making the noises, that and maybe a tree limb. My neighbors in the front also heard it. So today I go out to my side yard and my old rusted ladder I store in the yard is set up right next to my house in a position that someone tall and strong could pull themselves up onto my roof!!!!! WTF! I'm so fucking creeped out. What were they doing up there? Why? I have always said I don't need/want a gun but I have changed my mind.
