Funny, before I got to your post those were the two pages I had on tab! But thanks nonetheless. And what do you recommend for looking into Franklin?
I don't have any pages on him, but you might want to check out a documentary called "Secret Mysteries of America's Beginnings - Vol. II - Riddles in Stone - Secret Architecture of Washington, D.C." which talks about this stuff. The viewpoint is Christian so naturally it's skewed that way, but the data is well researched.
You won't find it on Google video as it was removed, but if you really want it maybe I can get it to you.
