I am not there now but lived there for a few years last decade. Washington State is fantastic and there is a sizable British community there (I am assuming you are in Seattle-Tacoma?). You will find something.

Where in WA do you live? Kinda like saying are there any Americans in the UK. WA is pretty big.

I live in the Bellevue area near seattle.

You may want to post a bit of what you are looking for or your background (i.e working, kids, interest).

There's a lot of us here, but it's a big state so someone is in for a day of driving if a Spokanite wants to meet a Bellinghamian (I have no idea what people from those cities call themselves). Most British people I have met out here work for Microsoft or Boeing but I've never really felt the need to seek out a group of British people since my American in-laws are supportive enough. You could try the meet-up forum.

The Brits in Seattle meet-up group has some good folks in it. We don't go to many events but we are a fan of their Pub Quizzes, they do a range of stuff, it's not just a pub orientated group.

I signed up to reply to this!
I'm up on Whidbey Island

I'll be there on 17 June. Living Downtown Seattle.

I would look for a Facebook group with a relevant title. (I know there is one for Aussies in Seattle - I'm a dual citizen and moving from Oz so the topics covered there are often relevant to me.)
