I received the following email this afternoon:

Subject: Cell phone app where users mark gun free zones

I built a cell phone app called GunFreeZone that allows users to mark and share where gun free zones are and which stores are firearm friendly.  The users can then make the decision whether to patronize that particular business or not.  We launched about a month ago and are just trying to get the word out – if you would like to do a post about the app, I can get you whatever other info you need (if you want graphics and so on).

The website is www.GunFreeZoneApp.com in case you’re curious.

Thank you very much for your time and response,

John Peden
