Since your rackspace is hosted in Corvallis, it only seems appropriate that you should include Oregon on your list of stops for the Serverfault world tour/DevDays-equivalent, whenever you get around to having it. Portland is a beautiful, fun town full of character with a wealth of tech presence including Intel, Tektronix, and IBM, and is a hotbed for open source -- Linus even lives here.
Portland also has a small-town chip on its shoulder for a city its size, which can sometimes come off in a slightly passive-aggressive fashion but means you would be treated as absolute rock stars the whole time you were here.
