If you don’t remember the last time you left the Square, it’s probably because, well, you just haven't. For an inexcusably long time. The sort of time that traverses past spring semester, the barren terrain of J-Term, and maybe even those deceptively serene days following fall move-in day. Get the point?

If not, the point is that you should probably crawl out from under that rock called Harvard (if you're here for the summer) and explore the bounty of events that awaits your fresh faces in Cambridge. The city has a series of exciting events lined up, many of which are outdoors, free, and within walking distance from the Square. Here are a few college-friendly ones:

Boomtown Festival 2010 (July 8 and 15, 6:30 p.m.)

This concert will feature free bluesy, jazzy, and soulful music, dance, and visual arts. So grab your picnic blanket (or that ratty towel that you like to use as an alternative, no big deal) and your friends, and take a walk down to Centanni Courtyard.

They Gotta Be Secret Agents (June 13, 11:00 a.m.)

The puppetry show at the Donnelly Field will consist of short segments of clowning, video, dance, puppetry, and theatre flow.

Inkas Wasi (July 28)

Held at Sennott Park, this event will feature a Peruvian music and dance performance by artists in current day Andean costumes and with traditional Inka flutes, unique percussions, and string-instruments.

Alastair Moock (August 5, 11:00 a.m.)

Mixing music and humor, the American folk musician will perform at the Kennedy Longfellow School Playground to showcase his music, anecdotes from his tour, and American history, to entertain and educate his audience.

Chinese Dance (August 17, 11:00 a.m.)

Founder and director of the Chu Ling Dance Academy, choreographer Chu Ling, will perform at the Hoyt Field for a range of audiences. She has performed at several colleges and universities in the Cambridge and Boston area, including Harvard.

Jungle Jim's Big Balloon Show & Inman Square Neighborhood Movie Night and Social (August 19, 7:30 p.m.)

A two-in-one package featuring a juggling show and balloonist, this event will be followed by a free move screening co-sponsored by the Inman Square Business Association. If you’re up for a night of family-friendly nice outing before a long weekend of fun, head over to East Cambridge Savings Bank parking lot.
