And some folks pull a tire! This kind of outing is serious work.
You can bring more beer along in a sled than a tire
At the start I had my pack and the hut in the sled. Then I carried those on my back while pulling the sled and eventually had to leapfrog either the pack and hut or the sled... but that did help to straighten my line out a little having something to look at other than white nothing. Could see the other side of the lake to get a fix on anything... and no beer! :-(
