i too have seen yotes int he lone and in large groups. they don't seem to effect our deer herd here in the deep south as much as they do for ya'll. they do greatly effect our beef market. yotes are hell on calves during calving season. one of my favorite spots to hunt is near a well used yote den. i have not found the den (not high on my list of things to find) yet but every year i hear the pups howling. especially when there is a distant siren of a passing emergency vehicle.
