The Mercatus Center has a study posted that ranks the relative freedom of the individual states. This is a combo of individual and business freedom, and the details and a map depicting freedom in shades of blue can be found at the link.
It's nice to see my own state, Colorado, rated at #7, although I seem to remember the place being MUCH less regulated not that long ago. It's depressing to think that 80% of the country is more like North Korea than we are.
Another interesting item is the way Indiana stands out, #3, in a sea of darkness like Switzerland surrounded by the 3rd Reich.
They mention regulation of air guns in Colorado. I was unaware we had any regulations beyond admonitions not to shoot out other peoples windows.
