Idaho Gun Ownership

I was visiting an area bar the other day with my wife and a sign hung in the entryway that read, "Check your guns at the door." I couldn't help but laugh at how that sign would be received in modern-day Idaho.

There have been political discussions about making background checks tougher, banning military-style weapons for civilians, and limiting the amount of artillery a person can buy in one transaction, but nothing to date that implies Americans will have to give up their guns anytime soon. Do these numbers of firearms reflect the most paranoid minds on the planet?
