Well, let me add Wyoming to the list. We're a free carry state. I don't have my permit yet but, I am planning to get it since it is accepted in other states. From what I understand, $75, DD214, Hunter's Safety, or a special class and the permit is yours. I'm not sure how long it takes to get it...but, I will update you when I get mine.
Still haven't got mine but, here's the information from the web -
$74 for app/fingerprinting
Valid for 5 years
Takes 90 days to get it
