Now I have a serious question, since I ride a motorcycle with locking hard bags am I in violation of the law if I get off the bike to open my bag and slip my pistol in and lock it up on school property? My truck is one thing I can disarm without setting foot in the parking lot, but to disarm when I ride I have to get off the bike to open the bag and slip my pistol into it.
Serious answer, use a cover, remove it, and put it in the locked bags. Nobody has to see a thing.
Not so serious answer: Don't wave it around in the air announcing you now have a new right. (I'll give you credit for already knowing this)
