Kimmy, I am so sorry for your loss. Your Granpa did have a wonderful, exciting life. It sounds like he lived life to the fullest, something we all wish we could do. I can imagine how much you miss him, he was your best friend.
Don went in the Navy at 18 and spent many years in there. He retired in the 60s. He was in heliocopters during Korea and Viet Nam. Once a Navy man always a Navy man.
Your Grandpa was one of our true Heros and I know he will be greatly missed.
Jackie
