The first four pictures were sent in by DS in 2012. He writes: "These are trough urinals at one of many public restrooms at the Sonoma County Fairgrounds in Santa Rosa, Ca. The fair is celebrating it’s 76th anniversary this year. The fair includes horse racing as well as farm & agricultural exhibitions, carnival rides and art exhibits. (Of note: that door in the second photo opens onto a screened walkway)"
DS continues: "Here is another of the many public restrooms at the Sonoma County Fair in Santa Rosa, Ca. The fair is in it’s 76th year and hosts agricultural and well as artistic exhibitions in addition to horse racing and carnival rides for the kids (and us adults!)."
This last photo was snapped by PB in 2016.
