I don't know who the big kids were with the special bibs and all, but wait a few days and you'll something from Oregon Velo, who posts dozens of photos from every Oregon bicycle race all sseason long. Sean's a working guy so it may be a few days before he gets usgp photos up; don't know if he's going to Bend or not.
Also, Pat Malach's Oregon Cycling Action site has a USGP write-up and some photos posted already.
Finally, check out Flickr for personal photos (search under USGP Portland or USGP 2009 or something like that).
Good luck --Beth
