Beretta, if I can....
I've made several trips across country at various times. When I have to go on a long multi-state trip, I take a binder with me. In said binder is a page protector for each state. ** FYI, some counties of a state have slightly different (more restrictive) laws than the state does**
Of course, I read over the laws for each state before I travel through it... however, this is my feeling on if I got stopped and wasn't following the law... (IANAL, PAYOR, IYGAINBYO... I am not a lawyer, Proceed at your own risk, if you get arrested im not bailing you out LOL) All of us are trying to follow the various laws. If we weren't we wouldn't have a concealed permit and would be "thugging" it.
If I got stopped and could produce documentation that I had very recently printed out just prior to my trip, and some goofy law had just taken effect magically a few hours before.. then I feel as though if I got stopped and wasn't following the law that perhaps that just might save my hide. I hope I never have to find out. Just my own thoughts.
Be safe and have fun!
