I don't know what the author is doing getting into the carrying of guns...somebody might point out that Illinois is the last state where there is no legal way for the people to bear arms whatsoever.
Well, that is not completely true.
Loaded open carry is legal in unincorporated areas, as long as you are not near a school or on public property such as a park.
Its just not real useful, and there are some other caveats that make it problematic.
