Morning, I am presently trapping beaver out of state and I have no options for drying the castor sacks. I do have a freezer with me. I am going to have to freeze them 'wet'. What is the proper way to do that? All in one container or frozen individually (laid out on a cookie sheet & then each in a baggie)? Also, (other than for personal use) do torn castor sacks have any commercial value? I've been skinning on the tail gate in the rain using artificial light for the last two days & have torn about 20% of the castor sacks.
