In in 1967 my dad was stationed in Korea. He left us in the OKC area since it was supposed to be just one year. That Christmas my granddad said all he wanted for Christmas was horse poop. My brother and I spent a couple of days at a friends horse ranch. We shoveled up a trailer load of manure and grandpa could not have been happier. The horse ranch folks had people come by all the time wanting the manure. They had the standard answer. You can have all you want but start with the barn. After you have that cleaned out you can have the easy stuff by the gate.
The USS Pueblo was captured on January 23, 1968.

My dad was home on leave and was supposed to be with us for 3 weeks. After two days the Pueblo was captured and the Air Force called him in the middle of the night and sent a car to pick him up. We did not see him for another year.
