Background: My name is Phil and I am the developer of an Iphone/Ipod touch application called "Legal Heat: 50 State Guide to Firearm Laws". I'm an NRA firearms instructor/concealed carry instructor and I released this app to help not only the general public to know and abide by the varying laws from state to state, but also as a reference to ourselves as we travel around for our classes. Thus far it has been a great success and thousands of people are using it every day (even though it's not nearly as good as it soon will be).

Help: As of yet the app only contains concealed carry laws for each state, reciprocity/reverse reciprocity maps, and transport law summaries. At the request of many people we are currently in the process of updating it with open carry laws, that's where I would love your help. To expedite the process and help me be as accurate as possible I would be extremely grateful for anyone who could summarize (or simply provide me statutory references) for any pertinent open carry laws you feel should be included in the app or that I should be aware of. It is an extremely difficult and error prone task to be undertaken alone, so that is why I am seeking your help. This is not meant to advertise the app, but simply to recruit any help that I can through this forum, I appreciate any info you feel willing to share.
Thank you
