Bikes on college campuses seems a perfect choice of a back to school reminder. Drive carefully around those bicyclists.
I went to Arizona State University (ASU) for college. The campus is extremely large and bikes were a good way to get around. We had over 50,000 students and the campus was over 1.5 square miles in size. We sometimes had 11 minutes to get between classes and it was very difficult to make it.
What about your schools? Were they large? Did you use a bike to get around?
