We used to be campers, we started early in the season and camped through October. If you have ever been camping in a camper you know the pleasure of laying in bed and listening to the rain fall on the roof. You can hear every little drop. So one night I spread 5# of bird seed on the top of the neighbors camper, right over their bedroom. They even found a wild turkey up there the next day! My neighbor said it sounded like little jack-hammers when they were woke up.
