By MARCIA DUNNCAPE CANAVERAL, Fla. (AP) — A moonstruck nation celebrated the 50th anniversary of Apollo 11's "giant leap" by Neil Armstrong and Buzz Aldrin at parties, races, ball games and concerts Saturday, toasting with Tang and gobbling MoonPies. At NASA's Kennedy Space Center, Aldrin showed Vice President Mike Pence the launch pad where he flew to the moon in 1969.
