Glad to see the graffiti has finally been removed, although the response time was regrettably slow. The City of Oakland and ATT would save a lot of taxpayer/ratepayer money by planting some grafitti-discouraging Home Depot $15 shrubs on the street-facing sides of these street refrigerators. That's gotta be cheaper than tying up resources to scrub off grafitti every few weeks or months. Seems like a no-brainer to me. The city should have demanded such effort when it granted ATT license to use public property for its for-profit devices.
