Yeah UCLA fan support has declined in recent years, but USC fans are still all over the place and very passionate. USC fans dominate my office / work campus of 4000 people. USC is probably the most popular collegiate fan gear I see on a daily basis. I've gone to several games over the years and there have been solid showings, given that more and more people are preferring to watch from home. I also visit my family in a different part of southern California and USC support seems to be very strong there as well.
