Thanks for the brain teaser Norm,
I always love seeing deer around the pond and put out apples,corn and salt for them. They even go out on the ice to drink around the aerator's hole in the winter. I'm glad we don't have any problems with snakes this far north but I think that unless a poisonous snake is ID'd that limiting their habitat by mowing and clearing is the best alternative to killing them all.In the case of a poisonous snake with my kids or loved ones nearby it would be a no-brainer.The King Snake suggestion might work as well. Once,back in Georgia, as I was getting out of the shower,one cruised across the floor of the old mill village house I was living in at the time; needless to say, I tore down the shower curtain and d n near had a heart attack trying to get away from it.
