I went to IUB for a semester during my undergrad. Traffic is definitely a problem. One thing I do like about the school is that there is a surprising amount of culture their for the size of the town. Big name concerts go through Bloomington, and it is incredibly gorgeous when the weather gets warm. When it's cold, though, it sucks. The campus is HUGE (compared to where I spend my undergrad) which is a pain in the ass when the wind chill factor is below freezing. At that point, public transportation is a MUST. I accrued $1000 in parking tickets because of the weather.
For the ladies, I even found a wonderful, classy, chic salon..Mira Salon del Dia. The owner is a fabulous lady from England.
