After receiving my permit in the mail about 8 weeks later, I decided I wanted to become more familiar with laws of other states and as such found the following book: Traveler's Guide to the Firearms Laws of the Fifty States. The book is written by J. Scott Kappas, Esq who is a private practice attorney specializing in firearms and self-defense law. The book, which a new copy comes out every year, covers each state and gives you an accurate, detailed description of the laws as well as the dos and don'ts of the particular state. If you travel at all I would recommend picking up a copy! I've read mine cover to cover for 2012 and plan to get the 2013 edition in the next couple of weeks. Check out the website here.
