Fifty of the 55. The very first post to start a page was Post 200 of Boiling Springs, S.C., which had representatives at the 2013 National Convention in Houston when the site was first unveiled in the exhibit hall.
What departments are not yet represented? Delaware, Hawaii, Mexico, Rhode Island and Wyoming. Posts from those departments wanting a leg up and bragging rights on centennial preparation should go here to start a page, a shell of which can be added to as information is gathered.
