Welcome to the site fishaholic! Good to see a fellow Wisconsinite.
We'd love to learn a little about you if you'd post an intro in the introductions forum.
I'll have to check the age of the freezer. I don't think its incredibly old, but I'll need to see to be sure. Thankfully, the energy usage from it isn't that bad even when looking at the new freezers. EnergyStar has a list of freezers and their energy consumption listed on their site. I don't have the link handy off hand though.
