I've been to Riverside a couple of times, and it's an interesting city to visit. The Mission Inn is a place well worth visiting, and other cool places to visit include the Fox Performing Arts Center, where a version of "Gone With the Wind" was first shown publicly in 1939, and the University of California, Riverside, which has a 161 foot high carillon bell tower on campus.
