Well it was cold (about 15 degrees) and the snow was blowing by the window, making almost a white out. So I decided to work out in the gym. None of the stationary bikes were working. I waited around and a stair master freed up. Took about a minute to realize this was not going go work with my knee. A few minutes later the rowing machine freed up. 5 minutes and 4 tenths of a mile later an eliptical trainer freed up. So I did 30 minutes on that machine. All in all about 3 miles. No walk in the evening as the kids were up for Holiday Dinner.
