We stumbled on it, totally unplanned in July 2010.
The photo below looks very much like a clip from the wonderful new movie about Facebook - Social Network, in that movie, the Winklevoss twins, Harvard students at the time, compete at Henley. These are the guys who sued Mark Zuckerberg, the Facebook founder and I discovered later that both Cameron Winklevoss and Armie Hammer who played him in the movie were there at Henley this year
Its a lovely town with great restaurants along the main drag
