In '69 I was on a search for a lost kid in Sequoia Natl. Park and came upon a nice sized rattle snake early in the morning while it was still cool. It was coiled up and no matter how much I poked it, it would only move very slowly. I left it there.
We see snakes here once in a while (only maybe six rattlers in eleven years), & I leave them alone or carry them over into the weeds/grass and let them go. This is the last one I saw two years ago in the shade of my tractor parked in the driveway. It rattled at first, but after I tried to pick it up with the mop handle, it just wanted to leave after a while. I finally got it onto the handle and put it up in the grass on the slope above the house.
