Student Tours The C-SPAN Campaign 2008 bus travels to middle and high schools, colleges and universities. Next time the bus visits your school, students can participate in a bus tour. Bus stops are usually 2-4 hours long. Teachers organize students into groups of 10-12 students. Student groups board the bus one group at a time for a 15-20 minute presentation conducted by a C-SPAN representative. The presentation features information on C-SPAN, our mission, the Campaign bus, politics and the media.
