Cleaning house! I have almost every issue (missing 5 tops) of MCN from the early 90's up to now.
They are in Seattle. Free to good home. You pick up. IMHO this is the best MC mag out there.
If you don't get any takers from this post, donate them to your local library.
I donate magazines all the time and they love it, that way people are able to check them out if they have more than one copy, but you probably already know how a library works. Ours won't let you check them out unless they are a few months old, but I live in the middle of nowhere.
