For someone so bright, she is awfully stupid. First rule of traveling with your gun, know the laws of the state you are traveling to.
When my mother got a CCW because she travels, I made simple summaries of what she could and could not do, how do carry, if the CCW was reciprocated in that state, dealing with the common Indian reservations she goes through and which ones to avoid, etc. and made her a booklet. I update it for her every year, even though most times I now drive her.
There’s smart and then book smart and I think she is probably the latter.
