An active Classic & Vintage group of bicycle folks here locally. Not a club, but a lot of nice people (guys, at this point) who love older bikes. Cascade has so many rides, that's the best place to start.
USFS has an active snowshoe program at Snoqualmie Pass.
Closest skiing is also at Snoqualmie, both X-country and downhill.
Excellent hiking trails close, too. Cougar Mt (Newcastle), Tiger Mt (Issaquah), & Mt Si (North Bend).
If you like the outdoors, it's all here.
Get a kayak - there's lots of water around us, too.
