Alta Vista Cemetery in Gainesville will be part of a worldwide ceremony Saturday in which wreaths are laid on the headstones of fallen United States veterans. It is the fifth year the remembrance will be held at the cemetery. The C.W. Davis Middle School band will play patriotic music to begin the event at 11:45 a.m., followed by a moment of silence at noon that will be observed at more than 1,000 sites nationally and overseas through the organization Wreaths Across America.
