This works great, until your mother-in-law takes care of your house while you're out of town and accidentally defrosts your freezer. Then any leaks in the frozen fish zip lock bags let the fish water drain into the bottom of the freezer, and even the items that should have been salvageable now smell like "old" fish...A tip for fish I read in Field and Stream years ago: Freeze it in water in ziplock baggies. I don't think we've ever had any more than 3-4 years, but it's supposed to keep damn near forever.
