Basically what @hypercat said. As far as Southern CA is concerned, Disneyland itself doesn't really have thrilling rides (in my opinion). But California Adventure has 1 legit roller coaster and Soarin' is pretty sweet. Six Flags Magic Mountain probably has the most roller coasters of all the parks in the area. People usually forget about Knotts Berry Farm, which actually is my favorite to go to for the roller coasters. Also yeah, fats everywhere.
