Bowhunter57, I agree that day calling is more fun in that you get to see the animal and its actions much more clearly. Having said that, I do like night calling and kill more coyotes at night all things being equal.
Interesting you mention people snooping around your vehicle. I was goose hunting years ago. I sat out field decoys in the pre dawn dark. I saw a vehicle stop by my truck 1/2 mile away while it was still dark. After the hunt, I found that they broke out a window and rifled through my truck. There was nothing to steal, but I expected they saw empty gun cases and were looking for guns. Sure wish I could have seen their license plate.
