Here is a great tip from one of our boot campers...
"When I was in college i spent some time in Berlin. Went to law school in DC -- Here's a tip for the cold to pass on. Put on your jacket, gloves, hat, scarf at least 5-10 minutes before you leave. You'll begin to sweat and feel uncomfortable so much so that it will feel really good to step outside into the nice cold air.
Of course. By contrast, if you wait to put on your coat until you're walking out the door, then you really never get warm. "
