I've co-written a gun-carry iPhone and Android app that I think might be of interest. This app is a crowd-sourced listing of anti-gun locations (stores, restaurants, etc… across the United States. Posted! - Carry List Anti-Gun Locations. iPhone/iPad: (http://itunes.apple.com/us/app/id530004581?mt=8) Android: ( https://play.google.com/store/apps/details?id=ryan.posted) I based this on what I and others I spoke with thought would be really useful! I always found it annoying to make plans with friends to go to a restaurant, only to be turned away at the last second because of their “no guns” sign, or to drive all the way to a store, only to find out I could not enter to buy the item I needed. This app makes it very easy to find locations that prohibit carry (based on current location, city, or name), so you know before going to one. And it makes it very easy to add such locations to the list (including picture, GPS, address, and description), so others will know where to avoid. I recently added the information from Northwest Firearms Forum's many "List of anti-gun stores" threads for Oregon and Washington. (I did this with permission and with attribution.) This is in addition to the businesses added by a few users. The description is below. Please let me know what you think! I’m always looking for ways to make it better. I am especially interested if anyone has any new posted anti-gun locations that haven't been already mentioned on Northwest Firearms. App Description: This application is for any gun owner! The purpose of this app is for the legal and conscientious concealed carry license holder to know where they cannot legally carry before getting there. A licensed permit holder or a resident of a constitutional carry state can usually legally carry their firearm in any location other than statutory "no carry" locations such as schools, gov. buildings, etc., and in locations that are posted prohibiting firearms. This is a list of those Posted locations. Find hotels where you can’t carry before booking a trip to one. Find restaurants where you cannot carry before making dinner plans. Find stores to avoid before you step out the door. It is extremely inconvenient to not find out until you get to a location that they prohibit your second amendment rights. You have to either disarm in the parking lot (causing your vehicle to be a target for thieves) or go somewhere else at the last second. If you know beforehand, you can avoid the places that prohibit carry, or you can leave your firearm at home if you must attend. So far, we have a comprehensive list of "Posted anti-gun" locations collected in Arizona, Georgia, Iowa, Kansas, Michigan, Minnesota, Nebraska, North Carolina, Ohio, and Wisconsin. We have assembled smaller lists in Delaware, Florida, Indiana, Kentucky, Missouri, Mississippi, Oregon, South Carolina, Tennessee, Texas, Utah, Virginia, and Washington; all provided by many great gun forums and sites with their permission. Since it is crowd-sourced by users like you, please be patient while the list grows! The initial Database doesn't have listings yet for other states. Be the first person in your state to grab data and add it to the app! You receive attribution for listing, and will receive special thanks for starting your state's listing! This list is user-updated, and will continue to get better over time. But this relies on you! If you go to a place not on the list and they have a sign, please add it with a few clicks via the "Add Location" button! If a place had taken down their sign, get it removed the same way! If you already have a list of anti-gun businesses in your area or state, please send me an email. We would love to include any data you have collected, and give you credit for it!
