Being on the water is so much fun. Especially when you can sing "I'm on a boat" with your sister and laugh hysterically.
We took the ferry from Boston to Georges Island, home of Fort Warren.
Given that this was a POW camp in the Civil war (the wiki link above gives more information, if you're interested), I couldn't help being reminded of Alcatraz. It's an eerie feeling, walking through history, knowing people were imprisoned here, isolated from the world.
Jill and I enjoyed walking around the island. It really is beautiful, and the view of Boston across the water was stunning.
