Bellingham here! It doesn't sound like there's really anyone close by but I've been keeping planted tanks for a couple years and occasionally post excess crypts, duckweed, etc on craigslist.
What kind of crypts do you post?
I'm on Camano island, but my wife and I spend quite a bit of time in Bellingham. I have a new 37 bowfront that still has some space for a few choice plants. Looking for some taller, larger species of crypt.
