I haven't been to Salish yet. Hard to hit them all with so many popping up all the time. Did you try their root beer while you were there? I heard they brew their own and my tavern is in the process of expanding and I'm going to have a root beer on draft and would like to use one of the local breweries for that if possible.
The SE area of Portland is where most of the better breweries are and there's actually very few vagrants on the street there, certainly less than University in Seattle. The light rail in Portland touches every part of town and is the best way to get around...I prefer to walk it myself, lets you sober up a bit in between places. There's a section of SE Portland where Cascade, HOTD, Commons, Base Camp, Lucky Lab, Lompoc, Hopworks, Coalition, and Migration are within 2.5 miles of each other. Throw in Green Dragon(Buckman Brewing...owned by Rogue), Apex, and Horse Brass for killer beer bars in that swatch of hoppy greatness and you have perhaps the best section of beer in the World.
The most similar area to that is in Seattle is in Ballard. 10 or so breweries in a 5 mile area. Love to start at Maritime Pacific...get the smoked onion rings and deep fried bacon and then start walking. You can hit Hilliards, Reubens, BAd Jimmy's, Populuxe, Peddler, Urban Family(Shelton brothers importer to boot), NW Peaks and then find your way to Hales. Have a snack there then hop in a cab to Fremont. Not sure what you've tried from Fremont but a lot of their specialty beers are some of the most sought after in the US. Their Dark Star Oatmeal Stout is probably the best stout brewed in the state. After Fremont roll over to Brouwer's Café for the lamb burger, a great tap list, and probably the best tap list on the West coast.
We should get together for some beer sometime....we'll grab Worms and have a day of it.
