Have been visiting for years. First off - ITS FREE. Why I have no idea because I think almost anyone would pay a few bucks to get in. Where else can you board the worlds first atomic sub!
Although not that large you really need a couple hours to see everything - don't forget the outside displays as well. During the summer there's a pretty good hot dog cart on the site, but in off months there are several very good dining choices within 5 minutes of the place.
