As far as core areas we don't really have so called core areas. The deer aren't as plentiful as the lower half of the country and they tend to still have the same range , but with the steep country and narrow river bottoms, and ravines that run top to bottom, they can be anywhere on any day.The most common denominator usually is bedding area spread out through out their range. The food supply isn't as concentrated as down south either so they feed as they wander. Any pressure will send them into different areas for few days until they move to the next area. We don't have a lot of agricultural areas in the central part of the state so making an out of the ordinary food plot is sometimes a magnet so to speak , something different that may peak an interest for a while.A wandering buck in rut can cover a 3 mile area and be on one side of a ridge one morning and totally on the other side of the mountain for the next four days. It is a little different than hunting bottom land or slight rolling hills . Its the same every where you hunt , you just need to adapt and overcome.
