In our first three years we got a lot of dog mushing stuff -- all that we now have to haul around.
We started out with a dog scooter, which was great for Denali and Rubi, and also worked fine when Holly joined the team; one or two dogs, no problem. But it's difficult to scooter on snow, and you don't want to even try on a frozen, icy trail -- trust us. So, for the winter you need a sled. A sled works with a small team of two, or a big team, 8 or more dogs, but not a scooter -- two professionals is the limit, at least for us right now. So we added the rig for dryland mushing with 3 or more dogs.
And finally, we added a fat bike for all those days when there's no enough snow for a sled and too much for anything else.
