If you’ve “outgrown” theme parks — or at least think you have — consider a stop by Six Flags Discovery Kingdom next time you’re in the San Francisco Bay area. It’s quite amazing, really, but Six Flags seems to have included enough attractions to keep every member in the family fully engaged during your visit. Some parks are a little too focused on aggressive, stomach-churning rides that older members of the family are much less likely to do than to watch.
