I've got a letter from the Sec of Transportation somewhere on this subject. I had heard this same thing for years. It's not true but many believe it.
You must have a permit from your home state.
You must follow the laws of the state you are in.
The weapon must not be accessable from the drivers seat.
The ammo must be seperated from the weapon.

There is more but that is what I remember.

Just remember that you will be sleeping in places at night most cops won't go in the daytime.
Load your weapon when you go to bed and unload it when you wake up.

Good luck and your instructor needs to show you the law that says you can't carry.
Be prepared for a long wait because it's not there.
