I got about 15 responses in a day or so to the "mystery photo", which, once again, wasn't too mysterious. To a person, EVERYONE identified Buffalo Bill Cody. Correctly identifying one of the Native Americans with him proved a little tougher. "Sitting Bull" was a popular, but incorrect response. The correct answer was either Long Bear or Chief American Horse. The gondolier's name was Coolio Schulman, but I didn't expect really anyone to get that.
The first genius with the correct answer was Judi B. A fine book will be winging its way to her shortly.
