CJ, could not read the obit, but none the less, this is hard stuff, at least it was for me, dad is still going on at 80, Lost mom at 60, just 10 yrs ago tomorrow, good stuff has been said here, and I herald it, He will live on in your life as you lead it, and pass his legacy onto your kids, and or family. Still leaves an empty hole in the spirit where He used to be, Physically. Try to fill it with the younger family, getting to know the nieces and nephews and let them know what your dad was all about, and allow them in to fill that place.
May your father sit at the right hand of God, and share coffee with those who went before him, that he cared about.
M25 who is not over his mother yet. She was the good stuff, my M14 is named Myrna, after her. It is the only firearm I own that has a name.
