As a science major I thought one of the best things about Duke was opportunities to conduct cutting edge research under the guidance of professors and graduate students. I was committed to gaining great research experience and Duke provided me with that better than a smaller private school or a huge public school could have. Socially I was a little less happy with Duke. Proviledged students were definitely over represented at Duke. Eventually I found a group that I felt comfortable with in PWILD, a backpacking club. Academically Duke was everything I wanted though.
When P.T. Barnum donated money to Tufts University, he did so on the condition that the school's mascot be named after his beloved elephant. The Tufts University mascot has been the "Jumbos" ever since.
