The bus system is very easy to learn and use. Because buses come about every 30 minutes, you should look up the schedule so you don't have to wait so long. They have paper copies on most buses, and you can look it up online as well. The buses go all over the CU area and are especially helpful for students who don't have cars or don't want to move their cars and lose their parking spot! The MTD is free for U of I students, all you have to do is flash your student ID and away you go!
