I came across this interesting article that also has, what I think is a pretty cool interactive map. My only complaint is that the map is a bit small. But I discovered that my home, which is in Morrison County MN comes out with slight lead in gun dealers. It would have been more fair to include ranges too, but it would have been a challenge considering it could be quite a job to find the data.
I don't really have anything deep or contemplative to say about this article other than its an interesting way to look at things. Thought I'd offer it up to the masses here to share.
