Chad,
I just graduated college last year and I can honestly say joining a fraternity was the best thing I did when I was there, It not only a bond that make with a group of guys but also with guys all over the country if you join a large one such as Kappa Sigma. I've met brothers from all over and it never fails to amaze me the instant bond I get these guys that I had never met before. So the only thing you should worry about is not whether to join or not, but which one you best fit in with to join at your campus.
