Well now I don't really know where to put this but does anyone here know If someone in North-Western Washington state lets people come and run trains or if there are any clubs? I live around the Everett area....

Try the NMRA site, they have a listing of clubs, might have one for modellers too.
Otherwise google may turn something up.
Good luck
Not much I could find, all of the locations are too far away from me to drive. I did find one place but it had no contact information.
The only one I know of is a club that meets in the Edmonds Amtrak depot but when I visited several years ago didn't seem too interested in getting new members, even when I mentioned I was an architectural model maker.
