<p>jonadam, are you asking about commuting from Ann Arbor to Detroit because you are under the impression that Ann Arbor is a small residential suburb and Detroit has a vibrant downtown area? If that is the case, do not worry. Ann Arbor is a self-sustaining city with over 100,000 people. It is very liveable for both undergraduate and graduate students. As most have already suggested, commuting from Ann Arbor to Detroit makes no sense. Heck, there are more people who commute the other way (work in Detroit and live in Ann Arbor) because Ann Arbor is such a nice and lively place to live.</p>
