The conversation during our three days together backpacking the Mount Rogers National Recreation Area this past Easter weekend always seemed to come back to nutrition. Grace, Lois and Alan had carted in enough fresh produce to start a farmer’s market at our Rhododendron Gap campsite. Conservatively, I’d guess they had 45 pounds of food between them. I was relying heavily on prepackaged, come-to-life-with-boiling-water dehydrated food, from instant oatmeal in the morning to cook-in-bag meals at night. Foodwise, I couldn’t have been carrying 5 pounds, if that.
