Are there any really thick areas, like a cut over that's 3 or 4 years old, that could be bedding areas? Do you have much topography-ridges, saddles, hollows, etc? Are those clearcuts on the adjoining property at the northwest corner? They were timber in 2013. Check for trails and sign along your property boundary-could be a good morning/evening spot. Look for trails/sign along the northern edges of your white oak flats.
In the lower left corner of your Google Earth picture, there is a "1992". Click on that and a slide bar with dates will appear in the upper left portion of the image. Just slide the tab to the various dates, you can see how the property has looked in each aerial since 1992.
Look at the 1996 image and you can see fingers of timber growing in an area that looks bare-immediately below your pin marked "Power Line Shooting House", but is planted on more recent aerials. Edges formed along different age patches of trees are good travel corridors. You can also see them in the 2015 image as bluish tinted trees-probably hardwoods-growing into very green patches-probably pines.
Hope this helps some.
