We're wrapping up a multi year project that went through multiple design changes, leaving us with a ton of material samples.  Does anyone know of a good place we could donate these samples to, to keep them out of the landfill.  I'm in the greater Seattle area.  Thank you for any suggestions.

I see Kjell Anderson, Mary Ann Lazarus and Daniel Overbey as the Green Gurus on this list - if i missed anybody apologies.

Congrats all around folks!
