I experienced the same thing when I moved for undergrad, and the school was not in a college town so there weren't too many other bored kids about to start school around. I suggest if you want to get out and find social local activites in your community that you try meetup.com. It is great for finding people that are intersted in the same things you are, and the activities range from free, to concerts and the like, to vacations. There are a lot of "Urban Adventure" groups that already know the town and will give you a group of people to explore around with.
Also, yeah.. reading.. but won't you be doing enough of that soon? ;-)
