Dennis James was at check-ins, and he is not GH15 (sorry to busy your bubble) - Dennis has an extremely busy schedule coming up, traveling around the world, which is great for him.
Phil Heath was there, supporting the legions of NPC competitors, and going to watch the football game upstairs on the rooftop at the hotel, where they have a projection screen.
Tentative schedule of events on who is going to go first Friday and Saturday was on the wall...
Many others too, as pics will be up later on bb.com...
