Reader Blair Ivey, inspired by the public transit pub crawls we devised for our 2009 Drink Guide, has mapped all of the bars in our guide with the bus, MAX and streetcar routes that serve them. A world in which TriMet's disembodied voices announce not only stops but nearby drinking establishments is now one step closter to being. Here are the results of his work for Northwest and Southwest Portland and for the rest of the city. Bookmark them. Use them.
