Ok I will bring the big one too lol. We get the IDHey there, HillBilly. You probably are ok with just your card, but I always carry my 8.5x11 signed and sealed recommendation.
Have been told by a cop that the difference to them is that if I show a Dr.'s recommendation with a signature and seal, I will be free to leave with my medication... but if I have some card that is not instantly ascertained to be valid, then they will take any suspected contraband and charge me with any illegal possession of suspected contraband. It will be my responsibility to prove otherwise in court.
Not sure if things always go down like that, but the conversation was enough for me to carry my rec at all times.
Photo then a small card size one that is signed and
Sealed then the full size up here but better safe
Than sorry
