Gun sales are up in Southern Illinois.  The area is known as a hotspot for hunters.  In fact hunting brings in millions of dollars of revenue for the region.  One gun shop representative says hunting season always brings in big business but come spring and summer, sales will drop drastically.  Sales aren't just up in Illinois.  More than one and a half million background checks have been performed in the U.S this month.  A background check is required on everyone who wants to purchase a gun, including current gun owners.  Those who aren't licensed must attend a gun safety course and get a FOID card.
