We grew up eating crayfish in Wisconsin. All the uncles and boy cousins (it was before we girls figured out how to get in on the fun!) would take nets to the local "cricks" and seine for crayfish. They'd bring home buckets full and we'd boil them with salt and dill... I think. It's been a long time! But first we'd all sit around and snap the heads off, and pull the middle tail fin out, hoping to get the mud vein with it. Then it was newspaper on the picnic table and we'd all be up to our elbows in crayfish shells - good times!
