Watch out for the little buggers preiscopeing you while your stalking. Look closely at their head, their eyes are more on top than the sides, this allows them to trot "OVER" the hill, or "APPEAR" to at any rate. They actually stop just over the rise and are out of site, but their eyes are actually just above the horizon watching you. In this manner they see wether you follow or not, if not they simply walk on over to next hill, if you follow they ease on over to the next county at 60MPH. All the while you dont know if their right over the rise or long gone as you cant see them.
