Greek life at Binghamton is not an all-or-nothing experience. Pledging a fraternity or sorority is absolutely not necessary in order to find friends but, in most circumstances, it will be a positive experience and introduce you to a lot of new people all at once. Some people become more involved in Greek life than others, and even if you do choose to pledge, that doesn't mean that it can prevent you from making friends outside of your fraternity or sorority. The Greek life at Binghamton is highly inclusive because the Greek presence at school is not highly visible. There are no Greek houses on campus to dominate the social scene.
Freshmen aren't allowed to pledge until their spring semester, and many of them attend frat parties, partly because they cannot get into other places. By junior and senior years, most people have outgrown these parties and the party scene, and even for those in fraternities and sororities, there is a shift toward the bars downtown. Many people choose to participate in Greek life because it is a unique college experience and a chance to make many new friends, but it is by no means the only way to meet these goals at Binghamton.
