A Sacramento suburb. Residing teens (many of whom are middle and upper-middle class) enjoy complaining about it and saying how awful and boring it is even though it is neither awful nor any more boring than other towns.
Folsom has its flaws, but overall, it's a good town. You can go to the lake, the river, historic Sutter Street, one of two movie theaters, Palladio (once it is finished and is not just movie theaters), golfing, biking on the various trails. You can enjoy nature in the wetlands, play sports, eat, among other things.
