If the first three were fun to build, why not build another? The Boxer is a two person, four wheel, pedal vehicle using similar materials and construction as the BigDog. Smaller, a little more "practical", and hopefully much lighter. See the DogSled build for what started, and continues to be the inspiration for these vehicles. Don't know for sure if this one will make it to Burning Man. It may end up with a flame effect, at that point I guess it would have to go.
