Anyone have any luck with those motion sensor lights that are supposed to frighten predators off? Apparantly predators don't like the bright lights. Hmmm....I have an extremely bright light beside my barn, lights up the entire parking lot and yet, I've seen coyotes standing right there. I wonder if the fact that the light only comes on when triggered by movement is what works, the shock factor or something. Any thoughts? The whole idea of motion sensor lights keeping predators at bay sounds hokey to me but if it works then I'm game for setting some up inside the barn.
