Dracho, you lucky son of gun!
I would love to catch one and I'd probably release him as well. Those snakes do a number on insects. You can't have enough of them IMHO!
My corns do the same thing. I thought they were going to bit me until I realized they were scared to death and rattling their tales to sound like a rattlesnake. I wonder how they picked up that trick???
I still think you ought to get rid of that snake of yours. There is a world of difference between rat snakes and rattlesnakes.
