The 107th camp of the Photo Odyssey was in San Antonio, Texas, home of the Alamo and 4 other old Spanish missions, as well as the famed Riverwalk.
Unfortunately, the organization that manages the Alamo bans photos being taken inside it, apparently out of respect for those who died there. I don't know how photographing a place shows disrespect, plus the fact that as I understand it, most (if not all?) of those who died there didn't die inside the Alamo but in the compound around it, but whatever.
So I focused more on the other missions, which, while far less famous and much less significant historically, were at least more rewarding photographically.
