Wow, good to hear.
I remember when I was a student, right before I graduated, I went and saw 'Saving Private Ryan.' I could not believe how many WW2 veterans were there. One of the guys came up to my row, walking with his cane, and yelled "Is anybody sitting there". I knew the guy was probably a vet and helped him get settled.
Stuff like that man....priceless.
FWIW, I really thought the book was awesome. Especially the part when they landed on the island.
I actually had a chance to go through the caves on the island and had a pic snapped on top of Mount Suribachi (where they raised the flag.)
I wouldn't trade those memories for anything.
