Solar powered mobile toilets are becoming available to San Francisco's homeless as the city expanded its 'Pit Stop' Program.
The new toilets rolled into San Francisco's tenderloin neighborhood Wednesday.
The mobile restrooms are available four days a week and stay open until nine o'clock in the evening, local time.
A paid attendant keeps them clean and stocked.
There's even a box to discard used drug needles.
People who use these pit stops say they are much needed.
"There's not a place to use the bathroom if you're homeless and don't have no money. You can't go no place and use the bathroom because they want you to be a customer," said homeless veteran Kaven Harris.
The 'Pit Stop' program is so successful that Portland, Oregon, Honolulu and New York are inquiring about the program.
