We don’t know exactly what set it off but somebody was busy with a spray can over the 4th of July weekend tagging a-frame sidewalk advertisements for various Capitol Hill apartment complexes from 19th Ave E to Pike/Pine.

This picture below from Twitter was claimed to show a tagger at work Sunday night.

With rents continuing to rise and City Hall so far powerless to do much to stem the tide, it’s possible the weekend’s blackout tagging was an angry response to the ongoing rise in the cost of Capitol Hill living. Or maybe whoever is responsible is a sidewalk muni code vigilante tired of what can be a cluttered pedestrian experience. Whatever the cause, the response was thorough if not elegant with apartments and condo buildings new and old included in the sweep.
