See the city from its streets and from the water with Boston Duck Tours. You'll take a ride on the amphibious DUCK vehicle and see important Beantown landmarks like the Boston Common and the Prudential Tower, and then you'll drive straight into the Charles River and see the city skyline from a distance. All the while, you'll have a tour guide telling you all about everything you're seeing.
Unconventionality at its finest is showcased at the Museum of Bad Art. Just like the name states, the museum is dedicated to the display and preservation of “art too bad to be ignored.” The MOBA is the only museum of its kind and holds a collection of nearly 600 pieces, and exhibits between 50 and 70 works at a time. See bad art in all forms, from paintings to sculpture, photography and more.
