It was -35*F last night (actual temp- don' even want to guess windchill!) Cold again tonight and tomorrow night. My Castine will be cruising at 650-700*F for a week straight with no break. I'll still need to run the propane heaters in the bedrooms to keep it at a livable 65*F inside. Well, at least there are no mosquitos this time of year Gotta love Northern Minnesota. Now I am going out to do some ice fishing. Lake Trout for dinner it is!
