The sense of adventure really starts to set in when we pick up our first small resupply box in Laguna Mountain. A cold, windy, foggy morning. We take turns getting warm by the heat lamp in the bathroom. We know we need extra water for the near waterless Anza Borrego trail ahead, but the hills, trees, clumps of boulders and soft earthy trail we’ve just walked give us no idea what to expect.
