Hotel on wheels. When the library closes, just ride the bus all night.
The VTA (San Jose/Santa Clara County) has a Route 22 that is known as Hotel 22. The longest ride in the county, it runs all night and costs $2.50. It was recommended that they shut it down but the usual suspects whined and it was kept. VTA figures show it costs at least $7/fare to run and that not counting all the obscured subsidies.
