Art, I'd rather fire off some rounds of 12 gauge #6 shot from my driveway in the air towards them. It wouldn't do much if any damage just a gentle shower of lead shot....... But then I'd get in trouble. Soooo, I'll stick with the 1 million candle power spotlight shined towards them at night, that clears them out in a hurry. During the day I don't really care if they are there. Actually if they are quiet at night I don't care either, it's when they go out on the high bridge and shout profanities just so they can hear their echo.
Gee, do you think that alcohol is involved....
