You are gonna laugh, but spicy slim Jim's. Or, any other spicy link style sausage cooked. The oils drive them crazy. I would keep a couple of slim Jim's on the pontoon for the little kids to fish with and they would hammer them on a float.
WHEW! I like Slim Jims BUT cost comparison puts them at about $237.23 a pound. Suckers are high as giraffe tonsils at the quick marts!
