Entertainment Weekly posted the link to this on their PopWatch blog. It was made by a Virginia engineer named Jonah Adkins. The maps and information incorporate details from the show and from The Lost Experience online game (which I've never played.)
I don't know how canonical the information on the map is, but one thing's for sure, the map is BIG. Also, pretty neat. I wish I had a printer that could print this thing out full blown in color so I could hang it on my wall, step back, and stare at it for a while.
No, I've got to believe that something about Shane would go in the wrestling folder. Is this about Ed McMahon? A Google News search said that he did the "Here's Johnny!" at the Emmys (which I did not watch).
