My sympathies, Sluggo. At least you can say you knew him, right? I was 7 when my oldest grampa (he would've been 98 this year) passed away and I don't remember him at all. Only a passing memory of sitting on his knees. I have a lot of stuff he has written over the years, though, mostly poetry.
My other grampa was a man of few words, quiet. He lived to be 90, and always left me wondering, things like: "Who knows how many people he's seen in his life!..." He did share a few stories about the war with us, though.
