When you are walking and hear a noise behind you, turn around to see a buck on his hind legs ticked off with ears back, they look a whole lot bigger than they really are. Especially when you have no gun on your person. They also growl like a dog.
I lived to tell this tale too.
Someone raised that buck on a bottle and then turned him loose in the wild. He had no fear of humans. When the rut hit, he went nuts.
There is a reason the law says you cannot raise a deer on a bottle. Doing so can kill folks or even kids waiting on school busses.
