Enjoying sub-zero temperatures

This is the rear entrance to the office towers I work in.

I keep wondering how many people usually wait for the shuttle bus to the underground station outside instead enjoying the substantially warmer environment of the lobby inside. On the other hand, they might be wondering who the picture-taking fool on the other side of the steet is...

A new thing is that I have modified the original picture which came out of the camera with ShiftN, a very useful program to correct converging lines.
