We headed over to the A's ballpark today (can't remember which corporation is sponsoring it this year), and were pleased to discover it was free visor/flag day, as this fan so aptly demonstrates.
Between innings, a roving reporter interviewed U.S. armed-forces families who were attending the game. Then they broadcast videos on the jumbo-tron from Kabul, Afghanistan, of Bay Area service people, sending greetings to their families. It was really moving and sad.
Despite its popularity in many countries, I still think of baseball as the quintessential American sport, and to see men and women serving in Afghanistan wistfully and cheerfully send us affectionate greetings at the game (a lukewarm pitching-fest between Oakland and Seattle) was almost more than I could bear. Best wishes to all service people and their families.
