Be prepared for emergencies—especially snack attacks.
Of course we have a spare tire, car jack, jugs of potable water, and a first-aid kit in our trunk. We even have AAA membership. But the thing we’ve found unequivocally useful on the road, time after time, are snacks. The healthier, the better. Our favorite driving snacks are dried mango, roasted almonds and cashews, buffalo jerky, and Clif bars. Sugary soda is best avoided, so we also take pains to fill and chill two 1-liter Vapur Element collapsible water bottles before setting out.
