Sled envy!

A twitterfriend known to me only as Documentally - a rich source of personal perspective material - has just posted this video of himself driving a dog sled. I would love to have a go at this. And I think my half-Akita puppy could easily be trained to do it - she's a strong girl who loves to be out in front, pulling me behind (except for walking, I'm teaching her that this is not how it's done).

The thing is, we've had 354 flakes of snow here today, so I'd need wheels on my sled.
