Submarine Visit Cartoon

UPDATED: Shown in the US Navy photo is USS Holland (SS-1) with visiting USNA midshipmen. The Holland was commissioned in 1900. Today, female middies often make submarine middie cruises.

Of the 4 nominees on the major party's tickets (Biden, McCain, Obama, Palin) which, if any has ever been on or visited a U.S. submarine?

If you know, please share the details (who, which, when, and where) with the rest of us.

The answer, which M.E. confesses not knowing, should surprise submariners no matter what it is.

Juan Caruso promises a cartoon dedicated to the first of you with a verifiable answer.
