I'll certainly add my sympathy to Corey, John, tracker and Richard to the losses of your Dad's. I was fortunate to have my Dad until 2004 when he passed at 91, however, he is still missed greatly. He was a master of everything and could fix anything that was broke or didn't work.
My Mom is now 92 and still lives by herself and drives to get her hair fixed once a week.
I understand your pain, and your feelings even though I had mine longer, except for tracker. The loss of a Dad is tremendous and my thoughts are certainly with the each of you.
