I've just recently visited Portland, Oregon, and it's such an enlightened city!
It's so livable that it bursts with opportunities for fun and frolicking. From the yarn store with a knitter's cafe attached, to swings in the very centre of the city. Imagine that! (If you're ever looking for them, they're on Davis and 8th).
They're not the best swings I've ever used in my life, but it was something new. I'd give them a 7 out of 10.
