It's true, we're suckers for lowercase, sans-serif fonts here at Haighteration.
We spotted this signage somewhere in the area. It's at the entrance to something... but what?
Update 9/4/2010: We have winners!
Commenter Nolan Caudill correctly IDed this sign from the car wash on Divisadero between Oak and Fell. Over on our Facebook page, Hilda Senseney got it right as well.
Congrats, Nolan and Hilda. Until next weekend!
