I am surprised to see that there is not a writeup for information on what to see and where to go around the Portland, Oregon (PDX) station. Wish I could help but since I am an east coast native I can't.
Anyway, I have two questions that hopefully can be answered. Is the Powell's bookstore walking distance from the PDX station? Also, is there a liquor store in nearby walking distance? I might have to replenish my stock on my next leg of my LD trip!
