College is just a little bit too broad. Way too many famous people.
My high school is just a small one though. I suppose the most famous would have been several professional athletes like Drew Gooden (saw him play in the CIF Championship), John and Tom Fogerty, Stu Cook, and Doug Clifford of Creedence Clearwater Revival, Martin Eberhard (founder of Tesla), and Amy Chua (Yale law professor and controversial author).
