re: Is it legal to have a loaded pistol in my truck?

It is definitely legal to be concealed or open in a vehicle. I've been pulled over twice before I had a permit. One officer asked me to step out so he could check it and the other just said "ok" after I told him it was in my center console.

And as for carrying in your car on a campus, by law you are protected, but I think this may be a case of state law versus school policy. Meaning, if the university finds out, they may be able to do some sort of disciplinary action even if you're protected by state law. You wouldn't be arrested or anything but who knows what they would do to you in terms of enrollment.

That being said, I am completely and entirely against any restriction as ridiculous as that. I'm glad LA had SB303 pass because hopefully that will open the door to more gun-friendly legislation. I'm all for it.
