The link I gave here is for HRO (hi res) images (less than a meter per pixel) from 2005. They have 2009 NAIP imagery for Oregon but it's 1 meter pixels. So it depends on what you are trying to do -- capture details for things like bike paths or get more current data possibly for new streets. I was going for details.

Thank you very much for posting this...I was struggling to get the correct URL going for USGS NAIP. Do you know if this is the 2009 stuff?
