Purdue Greeks are involved all over campus, including College Mentors for Kids, Purdue University Dance Marathon, Boiler Gold Rush, Purdue Student Government, and other activities. Activities and events Students at Purdue participate in more than 900 student organizations that cover a variety of interests. Some of the notable clubs founded by Purdue students include the Purdue Reamer Club (a school spirit organization that cares for the Boilermaker Special mascot and raises funds for scholarships) and two clubs that eventually became nationwide organizations: the National Society of Black Engineers and the Rube Goldberg Machine Contest. Several campus-wide programs are planned by the Purdue Alumni Student Experience (part of the Alumni Association), Purdue Student Union Board, Purdue Student Government (PSG), or the Purdue Graduate Student Government (PGSG). PSG and PGSG are made up of representatives from each of the university's academic colleges and give recommendations to the faculty, administration, and sometimes to the state legislature. Annual campus events include Boiler Gold Rush, Purdue University Dance Marathon, Spring Fest, and Grand Prix. Boiler Gold Rush (BGR) is Purdue's new-student orientation program. BGR, which takes place before each fall semester, was formed to ease the transition to college for incoming students and to help them get acquainted with successful college life. Boiler Gold Rush activities include speaker presentations from various academic, cultural, safety and professional organizations on campus, campus tours led by Team Leaders, academic 'meet the schools' picnic and interest sessions, late-night events at the Purdue Memorial Union, Recreational Sports Center and local stores, and a sports pep rally. Purdue University Dance Marathon (PUDM) is an 18-hour no-sitting, no-sleeping, dance marathon that takes place each fall in the Cordova Recreation center. Each year over 2,000 students participate and the event raises over $1 million annually for Riley Hospital for Children in Indianapolis. PUDM is also one of the largest collegiate Dance Marathons in the country. Spring Fest is an annual carnival with entertaining exhibits from many academic departments. A highlight of the weekend is the Entomology Department's Bug Bowl, where the sport of cricket spitting was invented in 1997. The Purdue Grand Prix, a 50-mile, 160-lap go-kart race is "The Greatest Spectacle in College Racing" and wraps up Gala Week each year. All 33 participating karts are made from scratch by student teams. The event has been raising money for student scholarships since it began in 1958. Religious life Purdue has a number
