E6, non residents get exactly the same protection as FOID card holders because of People v McDade. Go to the Illinois state police website -> Firearms / FOID -> How to legally transport your firearm in Illinois. Read.
WakingWolf for us Illinois residents it's unloaded and enclosed in a case, or nothing. However WW, you are right about an unloaded gun being useless in a stress situation.

I went to the Illinois State Police web site, and read about the Illinois municipalities with firearms ordinances:
http://www.isp.state.il.us/foid/ordinances.cfm
Now the municipalities do not have to submit the ordinances until 6 months after they are effective, so the list could be up to 6 months old.
But it shows 45 municipalities now.
===================
I looked at the brochure from the state police regarding firearms transportation:
http://www.isp.state.il.us/docs/1-154.pdf
I particularly like this question and answer...
HOW DO I TRANSPORT A FIREARM
THROUGH AN ILLINOIS COMMUNITY WITH AN
ORDINANCE THAT PROHIBITS FIREARMS OR
HANDGUNS?
Illinois’ Unlawful Use of Weapons law does not
preempt local ordinances from banning fi rearms.
Persons carrying or transporting fi rearms through
such communities could be subject to local fi rearm
ordinances. It is recommended that you contact local
authorities regarding their fi rearm ordinances.

I'm looking forward to the cite about
People v. Mcdade court decision
