Wow! That is really, really cool.....My parents were World War II era teenagers (graduated in 1945). My dad wanted to enlist when he graduated but he was 9 months too young, and his parents wouldn't give permission. I grew up hearing all of the stories and stuff.....That is really cool to have that insight into that era...So many of those men (and women, too, who served as nurses, etc) have passed on. God Bless your Grandpa!
