Since my grandparents liked going out on the boats, we thought they might like to look at more marine life. So we took them to the North Carolina Aquarium at Roanoke Island. The aquarium also had a dinosaur section!
My grandparents really liked the boats on the docks at the Dismal Swamp, so we decided to take then on a ferry ride in Norfolk, Virginia. The ride itself was around 15 minutes each way. It was cool to see the city from a different perspective.
