Once you pass Groton and EB on the Thames River (CT), heading under the 95 bridge you'll come to the New London sub base. Your life will be complete once you've experienced extremely motivated, highly trained US Navy Seal Shore Patrol armed with side arms and automatic weapons, with their weaponized overpowered shore boats, who with steeled deliberation and fortitude plant themselves squarely in your course (just to let you know they're there) to "escort" you, your boat and crew past the base. Makes me glad they work for us. The USCG doesn't have the pucker factor these boys possess; thank you G_d.
A number of years ago, before 9/11 My Brother was stationed at Groton.
The navy has a nice little golf course there and some sailboats you can rent. We took a sailboat out one day. My brother was fishing and napping, I guess I got too close to the Sub Pens for his comfort. He woke up, yelling get the H out of here! they'll shoot 1st..ask questions later..
