First off, welcome from Iowa.
I'm glad you realize the CCW badge is a bad idea. I've been seeing those in gun magazines for years. They say "This badge could save your life!" Yeah, right. No LEO is going to do anything but think somebody with one of those is a cop wanna-be.
As far as carrying your permit, I would just keep it in your wallet. That's what I do with mine, and in over 27 years of carrying there has been exactly one time an LEO has asked to see it, and that was when I was a bodyguard for a celebrity, and he was part of the team. Unless your state has a law that says you have to advise law enforcement in a traffic stop, it is highly unlikely you will have to produce your permit. Just keep it handy, keep your weapon concealed, and act appropriately at all times. Which means, by the way, you now have to take FAR more **** from people than you did before you were armed. You have much more responsibility. Take it seriously.
