Was checking my coon traps along a creek one morning, I caught a squirrel in a #2 Victor coil spring. It was more like a Conibear on that poor squirrel, caught him just behind the shoulders, obviously DOA. I guess he wanted some sardines.
Long ago, before my time, my grandfather used to wire the heart of a cabbage to the pan of his #2 Blake & Lamb Double Spring Jump Traps, and set for Snowshoe Hares.
