The City is increasing becoming a toilet bowl.  

Visiting to nice places like Union Square, Cesario's Restaurant, and The Marine's Memorial Club are still quite pleasant.   Although stepping over passed-out junkies in the nearby BART station, dodging aggressive hoboes, and hop-scotching over cow-flop sized human feces somewhat detracts from the overall experience.

A toilet-bowl -- in some ways quite literally.
Please remember to flush.
