Strangest thing you have run across while hunting

I have found a cave with drawings,rock bowls,etc.Lots of arrow heads,and stuff like that.In 1995 we caught a hog with two noses,kinda strange.Jumped a yearling lion up from a plumb thicket in 1994,there aint many of those up here.The strangest thing I have heard someone run across while hunting.My buddys Granddad was hunting a big ranch up here that is super rough.The dogs went off in a canyon and jumped something.A running fight took off down the canyon floor.The hunters were horseback up on the rim,they heard the dogs go to baying.It was very strange to them,there dogs didnt bay,they caught.But sure enough they were set back baying something.They rode around and found away down.Rode up ready to rope a whopper hog.Not a hog........Hyena.Like them ugly critters in Africa,yep Hyena! I think that is how you spell it.I cant remember what he said they did with it.But I remember him saying it was probably something somebody turned loose.This was in the early 60's late 50's.Kinda strange.
