Tapehoser, I believe you have it right. If you really think about it logically, gun owners and car owners are property owners - no one has the right to deny any lawful thing you do with that item, or what you store in it. That is why this law would be so good, it essentially says that private property owners do not have the right to deny other private property owners their means of self defense.
Ty, I am sorry to hear your state of affairs.

But, If you want to carry in the future this bill would at least allow you to leave your weapon in your vehicle as you spend your day doing your route. I would suggest then, that
you drive your vehicle to work, leave your weapon in the vehicle and spend that extra time on your route. If your employer asks about why your route takes longer simply state that you feel your safety and security is more important than the companies BS policy concerning weapons and that you are no longer going to "give" them free time in a personal effort to be safe when on your own time, whether that be on your way to or from your work.
