UPDATE ON SEPT 29: My dad's ashes will be interred tomorrow, September 30, at 11:00 am PDT. I'll be observing several minutes of silence about then, but in Central time.
Riverside National Cemetery, near March Field, is where my dad's memorial service was held on September 17th. His ashes will be interred there soon. It was a full military service: gun salute, the playing of "Taps," and folding and presenting the flag. The cemetery's flag was at half-staff in his memory that day, too.
