Jack, I'm really sorry we lost you at JenEllen's both nights only to have you get short-changed, audience-wise. Those no-show audience folks missed a great show, IMO.
Lane, you might ask Mousethief if there's anything happening in the Tacoma area. (Maybe I should rephrase that. ...Then, again, ...)
If you're into bluegrass, there's the Wintergrass Festival in Olympia, but that's in the winter (Duh...).
Rangeroger said there's a jam session --bluegrass, I believe--in Carson, WA, one Monday evening a month. What's that--about a 90-minute drive from Longview? It's close to the Columbia Gorge.
