Alaska:
That map is a huge exaggeration, and is a gross distortion of reality.
California law only makes it illegal to have a gun within 1,000 ft of a K-12 school. Many of the dots on that map are not such schools. They include things like numerous daycares, beauty salon schools, language schools, trade schools from truck driving to film school, Art schools, Seminaries, even an Islamic Learning Center.
For colleges there is no 1,000 ft rule. You just cannot bring your gun onto the campus of the school.
In any event, the situation is not as bad as that map makes it out to be.
Dear Oregon,
You are right that SOME of the schools in the other link are not included in the 1000 foot ban, but doing a different google search for only public schools doesn't make it come out much better.

For myself, it is quite impractical to consider open carry where I am at since I have a school right across the street. Every time you knowingly drive past a school zone with an openly carried handgun, you are committing a felony. Logistically, open carry in CA is prejudicially difficult by plan.
