There are two reasons that California has campus carry.

1. It is next to impossible to get a license depending on the county you're in so I just doesn't really come up

2. The issuing department can place its own restrictions on where and when you can carry such as only during work or no schools

Check out Calccw and you will find people who have a permit with a no school restriction on it.
