Cal Poly and UC Santa Barbara seem to be the coolest and most normal.

Berkeley kids are weird, Stanford kids talk about money and tech and understand money and tech.

State school kids are dumb (unless they have immigrant parents or are in grad school, or there to play a sport, band or choir scholarship)

There are some great Mormons, just like 10-15 potential mates if one is spouse shopping. Arizona is going to produce more physically attractive potential LDS spouses in general.

California students who are not Mormons admire the piano guys, BYU's Ballroom Dance, Lindsey Sterling, Benji Schwimmer the West Coast Swing former Missionary turned gay advocate.

In California UC schools they will make friends from all over the world, Russia, Belarus, China, Korea, Jordan, Nigeria, Malaysia etc., but that is becoming more prominent everywhere nowadays in just American schools.
