Running Vlog: Interval Timer

It seemed like time to do another vlog. There must be a better term on the horizon for a video-web-log. I thought the nature of this topic--how to use an interval timer--was pretty visual, so I decided to do it. I also think that it might actually help someone. I got the idea when I was showing Bill how to use the darn thing. It took me a few weeks to figure it out, and I am confident that I can get what I know across in about 4 minutes.
