On a day as bitter as today, I have to start this up. Consider the gauntlet thrown for those of you who live in colder places than MI in the winter. This morning it was SO COLD that I went to open the garage door and the spring that opens it had frozen and snapped in half. Now I can't get my car out of the garage until I replace the spring (or the whole unit?). The actual temp was -4 last night. It was a balmy 1 when I tried to open the door and it snapped. How cold is it where you are??
