Every undergrad at Harvard looks forward to NASD (National Alcohol Screening Day), otherwise known as the glorious camelback waterbottle handout day. These water bottles are desirable because….well who doesn’t want a free Camelback brand water bottle that normally retails for 20+ dollars? But also, these water bottles are a collectors item! Each year, students try to swindle their way into collecting as many water bottles are possible.
