Folks, please note that the chocolate peanut butter crunch cake we snapped Friday night, in front of these upstanding diners at Black Salt in DC, is untouched, reflecting the massive self-discipline that has made Mary and John Kane so successful. Mary, a former Maryland Secretary of State, has been CEO of Sister Cities International since 2011, representing 550 American towns in creating great relations with 2,000 partner towns abroad, and just hosted 160 mayors from China to celebrate 35 years since the program began. And speaking of China, John, CEO of office moving giant Kane Companies, recently returned from a nine-day trip to China with the Washington Board of Trade, praising the "tight supervision" of BOT chief Jim Dinegar, who evidently made them earn their Peking duck, running them around to visit 18 different American groups there. (Editor's note: All that said, under strict background rules, we cannot disclose what might have happened to those desserts after the picture was taken.)
