Braving it?

It is now Saturday morning and the temperature without wind chill is a balmy -10 degrees. The high is supposed to be -1. Although the coziness of my warm bed made me question my choice a bit, I'm wanting to run outside with other people. I'm meeting the group (which may only consist of me and Rebecca) at 9:00. There is no question we'll go, but how far will we make it?
