Here in WA, it's legal to carry a legally-owned pistol openly without a permit. You only need a WA CPL (concealed pistol license) if you intend on concealing or entering a vehicle. There are obviously areas, such as places barred to minors by WA Liquor Control Board, that are off-limits, but that just takes familiarizing yourself with the law.
As for carrying at school, let me put it this way:
1. I proudly own a GLOCK 27.
2. I am proud holder of a WA CPL.
3. I am a University of Washington student.
4. It is not against WA State Law to carry on a University or College campus unless their code of conduct says it is so.
5. UW Code of Conduct is contradictory on firearms possession, yet nominally in favor of carry (due to the contradiction of "no firearms possession", yet saying nothing is meant to deny constitutional rights).
6. I care about my safety.
You can pretty easily assume some things from the above that I won't state online until such time that I've graduated and have my degree.
