Thanks for your replies! The city of Portland definitely is a big draw for me, and I appreciate knowing about its accessibility. I'm aiming to get by without a car, so hopefully parking should be a non-issue in my case.
futureslpinca3, your comment about what you learned is really giving me pause. Do you think the courses weren't designed well? Or were there faculty that you didn't like? Do you think grad students would have the same experience?
