Use the college notice boards. My favorite way of meeting new friends was to put up a notice for the silly stuff I was into. I once created a very silly CTF, and put up a few posters, and got enough participation to make a few friends and had a lot of fun organizing. No matter what you're into, make it into an event, and put up a poster.
