Your dad was much like mine, a fighter in a great way! Sorry to hear of your loss as I too lost mine a few years back or yesterday depends on how you look at it, glad you had him so long!. It's not easy had a talk with a friend Thursday that lost his dad 2 weeks ago. He was alone on an aisle in Lowe's just staring a a box in his hand as I walked up, I know that feeling. Asked how he was doing and he slowly said not too good Mark, never taking his eyes off the box. We had a brief talk and as I left I said , it gets better, one day soon you will think of your Dad and smile. I am glad I was able to get close to my Dad in his last years, as you were, and it has carried me thru those rough patches when I realize I can't go ask his advice. Condolences.
