I would recommend not going to UMD, precisely because it's your home state and you would know a lot of people there, although this recommendation is strongly dependent on how extroverted/outgoing you are. Basically, if you're the kind of person who can make a new friend every week or two regardless of everything else going on in your life, disregard my advice, otherwise it may be valuable for your goal of meeting cool people to start fresh and build completely new social networks.
