Buggy Sweepstakes is one of two main highlights of Spring Carnival, a CMU tradition since the 1920s. Part high-tech soapbox derby race, part relay race, Buggy is uniquely Carnegie Mellon. In Buggy, student teams compete in a five-person relay race around Flagstaff Hill in neighboring Schenley Park. Teams are made up pushers and a driver. The pushers propel their buggy through the uphill sections of the course, while the driver steers through the downhill portions of the course reaching speeds of 35 miles an hour. Booth is the other main highlight where students design and engineer booths that include interactive components and sometimes are several stories tall!
