Yeah, cold weather's not that big a deal really... Like iFett said, you wind up getting used to it like you would the heat in the south. Personally, I hate summer the most and the heat, as I feel you can escape the cold, but the heat is what it is... You can only get so nude.
For me, having 4 distinct seasons is part of the charm of Pittsburgh (that and it's not flat. I hate flat). Summer gets old right around August, and Winter gets old right around the day after Christmas (maybe February). You start longing for those warm days, but then you get them, and you drop the top, and life's good again.

Today we hit the 40's which was a heatwave compared to what we had, so that made for a nice day in the old mobile office. Didn't hurt that work went smooth too. Tomorrow... Highs in the 20's, and the freeze is back on basically.
