Is It Winter?

I have been astounded this week by the number of people I have seen wearing shorts, short skirts with no hose/tights, and open-toe shoes. Has it not been the coldest week of the year? Do we not still have remnants of the last snow on the ground? Last night walking around the national tree, my feet got so cold in WOOL SOCKS that they were hurting and numb, yet I saw at least 2 people inappropriately dressed in their summer garb, no coat, etc. Maybe it's just me, but I'd prefer to avoid frostbite.
