Right now, there are backpackers crossing into Canada after five months of hiking the Pacific Crest Trail. They're called thru-hikers, and they started the trail in Mexico and will traverse 2,650 miles. Now, the lazy among us might have just read "Wild," Cheryl Strayed's memoir about the Pacific Crest Trail. The even lazier among us may be waiting for the movie to come out in December. The hikers who actually make this trek see toenails fall off and their feet can swell whole shoe sizes. They say the only thing they talk about more than their feet is food.
