I agree on the little green ones.When I was 14-15 I was on a two week work detail in April at Camp Big Island Boy Scout Camp in Rome City, IN (sadly gone now). The last Saturday was a free day after clearing brush and hauling dirt and building docks. A bunch of us decided to go on a snake hunt. Equipped with sticks to pick them up and paper grocery bags (before plastic) off we went on our hunt. We brought back a bag with 15-20 snakes, all around 6-8 inches long, and the counselor dumped them on the ground to sort. A couple were funny looking grey snakes which turned out to be water moccasins, 4-5 little green snakes which were rattlesnakes and a dozen assorted water and garter snakes. When they are little, with no diamonds etc. it's easy to mistake a rattlesnake for a garter snake. It made a believer out of me. Tinderbox
