About 25 years ago I built a 15X20 foot deck on the back of my house. With a roof. I really worked my tail off on it. Gold rope trim around the top. Nice siding along the walls. Coach lamps. I got it all stained and I was so proud. The next thing I know here come the doves. Crapping all over the place. Every day there would be 25-30 doves walking around. I couldn't get rid of them. I'd open the door and slam it and they would fly off. But 1/2 hour later, here they would be back again. I got a large sheet of plastic and covered the deck- thinking the wind blowing up and down would keep them scared off. They just kept flying in a landing on the plastic and kept crapping all the more. It was finally BB gun time. I started popping their heads off. It didn't take long before I had a freezer full of dove. I told the guys at my club about it. One said that there wasn't much sport in that. I said, I knew that, but It kept them from making such a mess on my nice new deck. I see them in the yard today and I still remember that.
