Re: RV and Cast;e
The Illinois State Police website states that for non-residents traveling with firearms in IL, the gun should be unloaded, enclosed in a case, and not immediately accessible.
As an Illinoisan (for now), I suggest you pick any or all of the other 49 states when traveling with a firearm!
Interestingly enough, once an IL resident gets his/her FOID card, they can carry an unloaded weapon in a closed container on their person, with a magazine in the same container, which makes automatics and fanny packs a big business here.
BUT, at Illinois gun shows "the (24- or 72-hour) waiting period does not apply to a buyer who is a dealer, law enforcement officer, or a nonresident at a gun show recognized by the Illinois Department of State Police." Go figure.
Several years ago I was on a camping trip out west, and was chatting with an RV owner about this very issue - home invasion in an RV. He said, "Well, I hate paperwork, so if anyone breaks in, they're not leaving til we find a spot down the road to dump the carcass."
SHOOT FIRST. SHOOT SECOND. MOST IMPORTANTLY, BE THE MAN WHO'S SHOOTING LAST.
