"Make your way to the Blackwater Wildlife Refuge about 10 miles south of Cambridge. You can take a self-guided tour. There are walking trails and you’ll likely spot turtles, osprey, and if you get lucky, a bald eagle and other wildlife. Because the forests, marshes, and waterways have changed little over time, you’ll feel the memories of what it was like for Tubman, who became an expert in working her way through woods, finding food, and locating hiding spots for slaves."
