Head into battle on the field at Boston Paintball. Recreational warfare at its finest takes place here on the indoor and outdoor fields. Professional or novice paintballers are welcome; there's also a pro shop on site so you can stock up on all your paintball needs.
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.
Experience an excursion in Harvard Square, a commercial and recreational center for Harvard students, city residents and visitors. Along with being a hub for arts and entertainment, and home to a number of attractions, shops, eateries, and places to stay, The Square is also a historically significant location. It was here that George Washington took command of the Continental Army, it is where the first printing press in America was located, and it has also been the grounds for many student protests – among many, many other things.
Spend some time hanging out in the country's oldest park. The 50-acre Boston Common is the anchor for the Emerald Necklace park system and is the starting place of the famous Freedom Trail. There are quite a few monuments throughout the park, and several outdoor events take place in the Common throughout the year.
