Most of the guys that I've known that have been hardcore muskrateers have seasonal type regular jobs - mostly construction. So when that slows down in the fall they have tons of time to run traps. One guy I know of trapped 4,500 muskrats last fall in a 3 state area. By the time he figures in gas/vehicle miles and other costs he says he loses money, but almost breaks even. He does it mostly for fun and to get/stay out of the house.
