The geocache diet

Here's a video that tells one person's attempt to lose weight through geocaching. While I think his goal is great, I don't think geocaching is the most effective way to lose weight. There are too many variables in geocaching to make it a reliable form of exercise. For example, you may not have enough long walk geocaches in your area. Once at the coordinates, you may spend a lot of time searching for the cache -- and that's time that could otherwise be spent on more intense exercise. Yes, geocaching is better than sitting on the couch, but it's no substitute for exercise that will do a lot more good, such as power walking, running, biking, etc.
