Founded in 1954, UC Riverside is home to 20,000 students, all of whom get unlimited RTA bus rides with their college IDs. Despite its setting in Southern California, UCR has a distinctly Scottish feel. All residence halls are named for landmarks in Scotland. The school's original mascot was a live Scottish terrier; today, sports teams are supported by a kilt-clad bear named Scotty. About 70 percent of UCR students are commuters, and freshmen do not have to live on campus. The university offers well-regarded graduate programs through the Bourns College of Engineering and Graduate School of Education. Notable alumni include Pulitzer Prize-winning editorial cartoonist Steve Breen, best-selling mystery novel author Elizabeth George and Nobel Prize-winning chemist Richard Schrock.
