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.
