Several years back, a colleague and I went on a business trip from Calgary to New Orleans in early December. The temperature when we left Calgary was -30 C (-22 F). The overnight low in N'awlins the night we arrived was 31 F - it was the first time in more than a decade that the temperature had dropped below freezing.

And yet, bizarrely enough, my co-worker and I felt like we were freezing because of the dampness in the air. I had never before quite believed the stories about "dry cold vs. damp cold" making such a huge difference. But it really does - dry cold feels bitterly cold on the skin, but the damp cold felt like it went right through to the bone. <img src="/images/graemlins/crazy.gif" alt="" />
