When I was an "Anchor Clanker" in the late Sixties, I was in a couple of ASW helicopter squadrons (HS-9 and HS-11). Those squadrons deployed on the Essex, Wasp, Lexington, and the Forestall. In all those tours, I never took the time to tour the entire ships. I think the next time I'm near one, I'll do the tour.
I toured the USS Massachusetts and the sub tied up next to it in Fall River, MA, back in the eighties. That was impressive. I also took the time to tour the Constitution when it was tied up in Boston, and I toured a 3/4 scale whaler in the Whaling Museum in New Bedford, MA.
If you ever get the chance, do it!
