I just finished replacing the battery on my tractor. I love working with metal hand tools when it's at or near freezing. It says it's in the high 30's here, but it was raining while I was taking the old battery out and the wind was blowing like crazy, so it felt much colder. The battery actually failed yesterday (while the sun was shining and it was in the high 50's), but I didn't have the opportunity to go into town yesterday. At least the damn thing starts.
Sometimes I really miss living in South Florida...
