That is IL. If a bow is in or on a motorized vehicle (and I believe any type of conveyance) a firearm, ML or bow must be cased and unloaded (cased and no arrow nocked if a bow). To my knowledge tThis also applies to ATV's, and I would not be surprised if it also applies to horses or other animals. I believe you cannot have any type of lighting on a horse for hunting coyotes at night while legally hunting coyotes when the nighttime hunting of coyotes is permitted.
