Sheeesh! 3C/37F this morning with frost on some cars and roofs. I started to get a "brain freeze" a bit when I started out (I looked for a buff but I couldn't find one, I'll have to make sure it is available for the next time I need it) but after 10 minutes or so, I got out of the shade and also started to warm up so it wasn't a problem for too long. However, I did make sure that I had gloves on but I could still feel the cold through them.
