Ok, if you are a history buff and love Delt (Im the same way), you will love this link,
http://delts.org/road/newmemberedchapter4.html. It is a list of PDF files from Sing to the Royal Purple 1989. Way.... more history than in the Men of Delta Tau Delta. It actually answers a few of the badge questions asked on here before and addresses very interesting info that for some reason isnt retold anymore. Enjoy Brothers.
