Rick of USS Batfish,
Since you're reading here, I just have to say, you folks really should shout it out on your web site and in your other materials that you have a great view into the conning tower of your submarine. That cage structure is a great idea. It's really quite unique. Only Razorback has better access of the 21 subs that I have visited, unless I missed one. On most subs, the conning tower is completely inaccessible or at best one can peek into it through a forbidding metal grating. To make this worthwhile, any text intended for the general public would need to explain the significance of the conning tower and its great importance to the operations of the submarine (I tell people, at least those who might get the pop culture reference, that they should "think of the bridge of the starship Enterprise with all its bridge crew, controls, and instruments, crammed into a walk-in closet").
Also, Batfish looks so exotic there in that grassy crater. It looks almost like it has been dropped there by space aliens. It's a very unusual siting with no obvious connection to the river, let alone the sea, and you folks should play that up. I understand how it got there, of course, but the decades that have elapsed seem to have erased any evidence of the channel that brought Batfish to that location.
Finally, just to reiterate, I really enjoyed my visit down there. Nice sub, nice little museum.
