As hundreds of backpackers head north on the 2,653-mile Pacific Crest Trail from Mexico to Canada, self-appointed volunteers known as Trail Angels will be there to ease the journey.
Some offer a cold soda, or a free ride between trailhead and town. But some actually offer free lodging and other services at their own homes. One of the best-known of these Trail Angel outposts is Hiker Heaven in Agua Dulce.
