I had just moved back to my hometown of Pittsburgh after nearly 40 years away. My friends came to visit me, they were both semi-disabled but able to walk around fairly well. So I take them on the Ducky tour. The woman gets seasick and almost faints, while her husband, an avid fisherman, is allowed to take the wheel for a moment. He almost steers the tourboat into some obstacle but luckily the driver regained control. That was the end of sightseeing on the water for us.
