The Pacific Crest Trail stretches from Mexico to Canada, a distance of 2,650 grueling, sun-scorched, bear-infested miles. When Dan White and his girlfriend announced their intention to hike it, Dan's parents-among others-thought they were nuts. How could two people who'd never even shared an apartment together survive six months in the desert with little more than a two-person tent and some trail mix? But when these addled adventurers, dubbed "the Lois and Clark Expedition" by their benevolent trail-guru, set out for the American wilderness, the hardships of the trail-and one delicious-looking cactus-test the limits of love and sanity.
