“By February 15 we will spread the empty sacks in the driveway in a big circle. In the middle we’ll pile provisions for the trail. I know from experience that the quantity of dog supplies will be shocking: seven hundred pounds of beef, six hundred of kibble, twenty-five hundred booties, to name a few. Everything will be bundled in small usable parcels. There will be 55 one-gallon bags of frozen beef sliced thin like pieces of bread. Thirty-five bags of salmon slices. A hundred and ten quart-sized bags holding five sets of booties in each. My musher supplies will also be plentiful. I’ll have packed thirty gallon-sized bags with my own food, and another thirty with personal items such as glove liners, heat packs, batteries, neck gaiters, and socks.”
