Wow, boydsdodge, I'm real sorry to hear about your Dad.
Like the saying goes, there's so much to do, but so little time. Think about what things that are of the most imprtance to you. Anything in your relationship with him that has ever bothered you? You want some resolution to something. Nows the time.
For me, as priderocks was noting, I don't know if you're religious, but for me, I would feel at rest if I knew my Dad had a good relationship with Jesus as his Savior. Other things will pass, but for me, knowing his soul will be at peace and with God, I think that is the one thing that would give me peace, knowing that I knew where my Dad stood with Jesus.
