So far we have been anywhere from 11-18F. degrees in the mornings the last couple weeks. Sometimes there is a light wind that will knock the windchill into the single digits, but it hasn't bothered me yet. We got our first snow here in Boise last Thursday and that has left some nice icy patches, but nothing too bad. I haven't found my limit temperature-wise yet, however, when it gets really icy I will draw the line. Oh, I have a twenty-four mile, round trip commute.
