Eleanor, the diff between a photowalk and walking and snapping photos is the group camaraderie.  There were probably 30 or so of us that walked and talked together while snapping away.  I noticed the James Dean guy as well!  Portland is full of character!  :-) 

I didn't know about VooDoo on The Travel Channel.  I didn't sample any this year, but I did last year.  I thought they were highly overrated.  And now I'll probably receive hate mail for saying that.  :-D  I do appreciate their quirkiness and originality though.
