I don't either - got rid of it when my state mandated registration for ARs - replaced it with a real assault rifle - an M1 Garand.
I carried..for years without a CC piece of paper. I did take the class...though.
Then OK...became an OC state...and free to CC....
I've not seen or heard of any problems...
Maybe if other states...adopted these "ideas"..there would be less BS going on...
