Snopes covered this last year when talk radio was whining about Obama on Memorial Day.
On several occasions in just the last thirty years, U.S. presidentshave been elsewhere on Memorial Day (either vacationing or attending to other presidential duties), while other administration officials represented them at the wreath-laying ceremony:
In 2002, President George W. Bush was in France on Memorial Day and participated in ceremonies at Normandy (site of the D-Day landings) honoring the U.S. soldiers who fought and died in WorldWar II. In his place, Deputy Defense Secretary Paul Wolfowitz laid a wreath at the Tomb of the Unknowns.
President George H.W. Bush (himself a World War II veteran) attended no ceremonies at Arlington National Cemetery during his four years in office. In 1989 he was in Rome on Memorial Day (where he led observances at an American military cemetery south of that city), and from 1990 through 1992 he spent the Memorial Day weekend vacationing in Kennebunkport, Maine, while Vice-President Dan Quayle laid a wreath at the Tomb of the Unknowns.
(NOTE: President Bill Clinton has no entry in this list because he attended Memorial Day ceremonies at Arlington each year throughout his eight years in office.)
I'm not seeing taking off to play a round of golf anywhere in there, though. :p Bush gave up the game, and Clinton didn't play on Memorial Day. :p
"The individual has always had to struggle to keep from being overwhelmed by the tribe. To be your own man is hard business. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself." Rudyard Kipling - (1865-1936)
