SF tax dollars would be well spent if they opened up a showering facility for the city's homeless. The restroom and elevators at the otherwise beautiful SF Public Library smell so bad I opted to walk 4 flights of stairs and use the one hidden restroom in the back that no one knows about. There's also a guy sitting opposite me looking scruffy and thumbing through catalogs called "Knives 2005" and "Guns Digest". He's wearing a US Postal Service cap. I'm not making this up, I'd take a covert photo, but that's probably not a good idea.
