Ive seen one deer cahsing one other deer through the woods in 2+ years hunting. Other than that.....every deer I've ever seen was walking.
Again....I hear them 90%+ of the time before I see them.....unless (as Scott eluded to) it's been raining. Even early season I hear them, first.
Dunno......I've never known anything different. Also, though....I hunt NO fields. I can rarely see over 40 yds or so.....so there might be deer that other people see in their setups that I would NEVER see because of the foliage where I hunt.
That's why it's so cool to see how other people hunt. It's probably VERY different than we likely think it to be.
