A friend of mine is the chief organizer of this event again this year...he makes it sound like so much fun. If you're in the Oklahoma area...Enid specifically, this would make a great family day outing.

It's a great cause for a fund raiser...actually two causes this year, Habitat for Humanity and the SPCA. They'll be set up for on-line contributions.
I'm sure there must be antique shops around that you could look for McCoy, too!
