I live in Cedar Falls, IA, adjacent to Waterloo, where the Sullivans were from. They have a big convention center named for them here, as well as a full military museum, with the history of the Sullivans as its’ centerpiece, along with a P-51D Mustang dangling from the ceiling of the place.
I was on the third USS Juneau, LPD-10, and there was still a connection to the first Juneau and the Sullivans. Juneau was decommissioned a couple of years ago and it will probably be a long time before there is another one, if there ever is.
