Although this SFist contributor couldn't make it to the little bluegrass concert in the park last weekend, we kept hearing mention of lots of hippies saturating the event. To echo that sentiment, friend of SFist and Outer Sunset resident Kevin McCracken snapped the above photo of a brilliant sign that was on the door over the weekend of local poster printing business, Moon Editions, which is located at Irving and 41st Avenue.

The sign reads, "NO HIPPIES," and then in small print, "No seriously -- piss off."

We sympathize with those who live and work near the park during these epic weekend events. It must certainly be a love/hate relationship.
