Tufts sophomore and photog Ian MacLellan posted photos from the kickoff of Tufts Sleep Out, part of the Leadership Campaign/Mass Power Shift initiative to raise encourage state legislators to pass a bill mandating 100% clean electricity by 2020. The first sleep out was held on Oct. 24 in acknowledgment of the International Day of Climate Action.
