Still on campus and looking for something to do? Radio 92.9's annual EarthFest concert is happening today at the Hatch Shell in Boston, beginning at 11:00 a.m. This year's performers include Eve 6, Switchfoot, Spin Doctors, and Third Eye Blind. Beyond providing music to the public, the concert seeks to promote an understanding of the environmental problems facing our planet. As a result, you'll learn a lot about green causes and be privy to a plethera of delicious (and probably all-natural) food samples from green-minded companies. Oh, and the concert is entirely free. So if you're craving some hummus, good music, and a day out in the sun, grab your friends and consider heading over to Boston for the afternoon.
