I had given a friend of mine the bucks that I and my son had shot last year,he had a friend who was wanting to start learning taxidermy and needed some to start with.After finaly tracking them down this month I find they have never been skinned out and are still in a freezer.How long are the hides good if they have been kept frozen?Or will I have to buy new hides when I take them to someone else to be mounted?Thanks for any advice given,,,,,,,,,,,
