He wasn't the only less-well-known-in-America athlete present (there was one from Costa Rica, and a speedwalker that I wasn't familiar with). Baseball, basketball, American football and ice-hockey stars were there in force - but sorry, I didn't know any of them; politicians such as JFK and Clinton (Hillary Clinton, that is); various rockstars; Justin Bieber (a nice bit of cross-dressing); stars of screens big and small; several beauty queens, but also (aspiring to something more substantial) women artists and scientists. Julie Andrews. Bill Gates. Elvis. The Wright brothers. Frieda Khalo. To name but a few. Special mention to one of the Boy's good friends, who appeared as a rather magnificent Moctezuma.
The Man adds...I've been making a splash in San Jose too this week...conferences are tough work but someone has to do it.
