Ive seen similar situations.. I shot at a group of hogs and they ran into the woods. We stopped shooting and I scanned and noticed deer right in the wood line where the hogs ranOn a side note, similar to this subject... The hog I shot last week was in a hay field about knee-thigh high. When I shot, 3 deer that were bedded down and completely undetected jumped up about 25-50 yards behind the hog. Had I known they were there, I wouldn't have taken that shot.
We stalked up to about 75 yards from the boar and could see him very well in the hay.. The deer, not a trace until right after the shot.
