All college campuses are different. For instance, at the University of Cincinnati, I find it completely illogical to use a bicycle for transportation between classes. There are stairs EVERYWHERE. I am not kidding. No matter where you are walking, you will find stairs. It is completely inevitable. The buildings on campus are also relatively close to one another (it takes approximately ten minutes to walk from one end of campus to the other) that having a bike isn't truly necessary.
On the contrary, you have college campus such as at The Ohio State University which is much larger and more spread out than Cincinnati's campus. This would allow for much more area to ride and biking would save you some trouble instead of causing more.
Don't get me wrong. There are plenty of people at the University of Cincinnati who do ride their bikes to class. I laugh at them when they carry their bikes up and down the stairs just because it looks like more of a hassle than walking. Plus you don't have to worry about locking it up when you get to class.
So it really comes down to this: If your campus is very large and spread out, bringing a bike is probably a good idea, even if you do not use it everyday. If your campus is small with all of the buildings squeezed together, you should probably leave the ol' ten speed at home.
Some of the different vehicles I've seen people get to and from class with include skateboards (I tried this once and may have fell on my ass, but that story is for a different time), razor scooters, bicycles, roller skates, longboards (welcome to Miami Beach) and even stilts, that's right, stilts.
If you do choose to use your God given gift of feet, please remember: Just as they cannot drive properly, they cannot ride. They will hit you. I've seen it happen.
Have a great next semester!
