$1.00 U.S. says this photo was taken in a reception line at the NRA event for high dollar contributors and others who bought tickets at CPAC and that Allen and Heston had no idea who any of these guys were.
I'll bet your right
I'd agree with you. Especially considering Heston's participation in the Civil Rights movement long before it was "cool" or safe.
Al Gore surely knew well the person who was a major fundraiser for his 1988 campaign and whose home he visited. He's the man on the left of both photos -- Fred Phelps.
