I’ve been to Portland quite a few times, though not as many as you might think given how far it is from San Francisco. It’s a gruelling full-day drive—I know because I drove it enroute to Vancouver earlier this year. Then we drove back.
I’ve neve really spent real “Portland time,” though. I was always staying either in a convention hotel or out of the city center. Technically, this time I wasn’t in the city center either, but I took the TriMet Max light rail, and it was awesome.
I got within three blocks of everything I needed to get to, and wound up exploring a lot more of downtown Portland than I’d ever seen.
I’ll be back.
