It's been years since I've connected with the Portland group, but it was fun back in the day.
There is a "PNW" Tesla Owner's group that covers WA, OR and ID. Yeah, it technically overlaps the Portland group, but they know each other and are cool with it. If anybody is interested in the PNW owner's group (which don't compete with a forum like TMC; they are more about IRL events) they are HERE.
Oh, and I'm from Redmond WA. We own a 3 and an X. We've been owners since 2009; our past cars are detailed here: Which Tesla should you buy? A decade-long comparo: Roadster, S, X, 3.
The Portland group is still active, though fewer events this year than last year. Phil just started an events committee (yesterday) to get things happening again. I wonder if he's reading this thread?
I looked at the PNW group's calendar and everything on it looks mostly Puget Sound region focused. Which makes some sense, Puget Sound has nearly half the population of the region. I have thought about some kind of drive event with a meet up between the Puget Sound group and Portland would be cool, but the halfway point on I-5 between Seattle and Portland has a supercharger, but not a whole lot in attractions as a destination.
