No. I have been to my father's grave once since he died 53 years ago. My mother was cremated and scattered at sea, so I guess technically you could say I visit her every time we go to the ocean, but no. We (my siblings and I) didn't have the greatest relationship with my mother, and I am the only one who remembers my father, so I guess it's not surprising. We also don't do "happy heavenly birthday" or anything like that (although this is a timely thread as my father's 106th birthday would be in 2 days... July 30).
One summer my sister and I did a cemetery tour, though. We found our grandparents', great grandmother's, and great aunts' grave sites. These are people we remember, so it was interesting but not sad or morbid in any way. We visited our dad's grave and discovered it's in the same corner of the cemetery as three sets of aunts and uncles (my dad's sisters) and a close family friend whom we've always considered an aunt, so that was interesting to discover. Finally, that summer my brother and sister came up and they, DD, and I drove out to Thorndike, ME, which is about an hour and a half from where I currently live. We'd learned that my great-grandmother and her family were originally from Thorndike, so I did a little searching on Ancestry for some details. We went to check out the cemetery and I have a picture of DD standing at a family gravesite; she's the 9th generation descendant.
