My mom told me a long time ago they went to the US consulate in Kobe, Japan on July 4th. What she remembered was having Coca-Cola. At that time that was special and hard to get in Japan in the early 1950s.
My memories of the Fourth were of an airshow followed by fireworks over a bay. We could see it from our house. We lived up the hill from the water. (Is being a mile away considered beachfront?) One year a man in an experimental plane died in a crash.
