You left out Next Adventure! They are a ULA pack retailer.
Many of us are waiting for that Montbell store!
Six Moon Designs is located in Beaverton (west side of Portland) and now has a storefront presence, so you can go directly there. It's probably a good idea to call first, though.
There's a place in Troutdale that I still haven't visited called "Only the Lightest Backpacking Equipment"–it appears to be a home operation rather than a retail store.

I really should call for an appointment and go see what they have. Lots of interesting stuff on their website.
There's also BackcountryGear.com down in Eugene. They have a store down there and do a lot of internet business. Right now they're having a rare sale on discontinued versions of several Western Mountaineering bags. I've bought quite a bit of gear from them in the past.
