The first property that you have sounds a lots like I have. The best thing to do is just like anywheres else, look for the funnels! Look for the "edge factors" too, fence lines, fire breaks, and old logging roads, where two or more different terrains come together. Deer love these places! If you can set up along the edge of a clearcut, where it joins a tall plantation, or a hardwood creek.
One of my best places was overlooking, an overgrown clearcut. I mainly had only two shooting lanes. One was part of an old logging road and the other was just a lane that was cut through the new pines. There was a narrow strip of tall pines and a few hardwoods that ran trough this clearcut. My shooting lane ran along side a portion of this strip. Across the logging road was a tall pine plantation, with a creek bottom on the other side of the plantation.
If you have any areas like this they would certainly be worth looking into! Find where they are crossing and you should have a good setup!

As for the second place, thick pine plantations like this are very hard to hunt!
You almost have to hunt the logging roads and fire breaks! Everything else is just too thick! Look at some aerial maps and topo maps to find whats around the plantation, this should help you figure out where the deer are comming and going to.
For thickets like this its your best bet to find their travel zones and set up there.
One thing I had to get in my mind is "you can't setup to see everything!" But it is better to hunt one or two shorter lanes in a good area, than to hunt an area that you can see a whole lot of nuthing! Good luck!
