I've loved living in the dorms this year. I've been closer to Shimer events, I've found it much easier to get to know people, and I've enjoyed sleeping in until 9:30 and making it to a 10:00 class! Plus IIT has some cool things I've gotten to take advantage of, like the gym. Apparently there's a pool, too!
That being said, I have no intention of living on-campus next semester. I have several reasons for this. Firstly, it's significantly cheaper. Secondly, I'll be closer to work and church. Thirdly, since I'm working in Chicago over the summer I'll need a place to stay, and I'm probably going to have to sign a year-long lease anyway.
