If you are at one with the wild and live in Missouri you may be out of luck when on a road trip. In this state it is illegal to drive around with a bear that is not properly contained with a cage. So, no uncaged bears calling shotgun. If they are caged, however, you should be in the clear. Just make sure you pick a vehicle that has enough clearance or you may have an angry caged bear on your hands, and that makes for some seriously unpleasant stops at the rest areas.
