Concrete wingwalls are common features at road crossings that can help you catch more critters on your trapline. Mink and muskrats are constantly traveling along waterways, and their paths tend to be funneled through bridges and culverts at road crossings. Below is a location where I noticed animals moving along a the concrete wall, and entering/exiting the water right at its edge.
A simple 110 conibear set at the edge of the wall has resulted in my catching numerous muskrats and a mink this season. Finding places to put in quick wingwall sets can certainly increase success on the trapline.
This not a comment it is a question. Can I catch a muskrat in a pet carrier drive it 15 min. away
