I guess I'll not wear shorts and a tee shirt, maybe put on a jacket. Truth be told, even by Montana standards, this is getting to be a pretty cold/snowy winter. We are already over two feet above normal snow fall for the area. We still have a lot of winter to go. Might get a little wet around here in the spring when all of this melts.
