You can spot orange a long ways. Since no critters I know of wear orange, hunters would assume it was another hunter.
Husband of a cowroker was out on his horse in northern NV one year checking on some cattle on an open range - not only was he wearing a blaze orange coveralls, his horse had a blaze orange saddle blanket on him. Some jerk shot his horse out from under him thinking it was a deer. That "hunter" lost a lot that day - his truck, his gun, his freedom, replacement cost of a horse, etc.
NEVER assume anything.
