'Hotel 22': Silicon Valley's All-Night Rolling Homeless Shelter

The 22 bus runs through wealthy Silicon Valley, from Palo Alto to San Jose. During the days and afternoons, it's packed with commuters headed to and from tech jobs. It is also one of the few 24-hour bus routes running through sprawling Santa Clara County, which is why by night it serves a very different function—as "Hotel 22."

With one of the longest routes in the area—a two-hour trip from end to end—the route is an improvised nighttime shelter for the area's homeless. For the price of a monthly bus pass, overnight riders can count on a relatively safe, rolling place to lay their heads. At the end of the line, they climb off, often carrying all of their worldly possessions in suitcases or duffels, and wait to board the next 22 bus going in the opposite direction. That's two more hours of shut-eye.
