A lively group of squash players in the Royal Marines are touring the U.S. right now. Most of them were on two previous tours to South Africa in 2007 and 2010, so they know the standard operation procedures of a tour and are having a great time at it. We hosted them in Philadelphia on Tuesday and it was great fun, a lot of various racquet sports in addition to the squash singles. At dinner afterwards, the four Pommies I sat near told me about their times serving in Afghanistan. All had been there at least once. One guy had just returned two weeks ago and was heading back for another tour next month. He admitted it was tough, especially because there are no usable squash courts left in the country.
