Boston Tour Guide
The amphibious Duck Tour boats are easy to recognize, and the tours are a popular way to see the city from both the streets *and* from in the Charles River.
Each tour has it's own "coDUCKtor" who provides a running commentary about the sights, and the passengers are encouraged to "quack" at people they see on the street. The tours cover all the major highlights on land, and give you a bit of a thrill when they chug into the Charles River for a trip that shows off some great views of the Boston skyline.
