My wife and I plan to take a road trip in a few weeks from Mississippi to Iowa to visit family. We'll pass through Tennessee, Arkansas, and Missouri. We then plan to drive up into Minnesota and possibly Wisconsin. An option on the way back would be Illinois, where I know neither I nor anyone else can carry. I have a Mississippi Firearms Permit and have undergone approved training and have received a special sticker on my permit that reduces the places where I am not allowed to carry. For example, I can legally carry a concealed firearm on a school campus. It's easy to get information about whether the above-listed states will honor my concealed carry permit, but I would like to know more about requirements and restrictions concerning having a firearm in my vehicle, particularly in Illinois, which seems to be generally hostile to gun owners. (I'm not remotely considering driving into Chicago!) I'd appreciate information based on experience traveling in these states.
