The 2015 Challenge, post script (1)

That evening, I attended the Challenge dinner. (So did Mrs B - it's one of the privileges of 10, 20, 30 and other multiples-of-ten timers, to be allowed a guest at the Thursday night Challenge dinner). Somebody took this rather nice photo of the 10 and 20 timers (there were no 30 or higher multiples of 10 this time). No idea why it's in black & white not colour ... but there you go.
