Ahh, the Conestoga wagon returns, minus the oxen. Did anyone else notice the bolt/wire/lock cutters on the side?

That's pretty cool. I might also suggest training your dog, if big enough, to pull. All my Sammies knew how, and one was even a weight pull champion. If you don't have kids this can haul extra supplies. Of course it all depends on the terrain. A set of runners for winter would be good.
