I spent last night on a retired WWII submarine moored in Baltimore Harbor, the USS Torsk, with my oldest son’s Cub Scout den. The Torsk sunk the last enemy ship of the war and holds the record for the most dives of any sub, at nearly 12,000. Now, having 12 kids and 11 parents locked in a tin can overnight is an experience in itself, but even briefly living in conditions similar to what our submariners endured (and still endure) for weeks a time underlines the unpayable debt we owe to those who stand watch as we sleep, and especially to the 52 subs lost during WWII, their thousands of crewmen “still on patrol” until the Last Day.
