We use to drive the pine plantations in the middle of the day since they are good bedding areas. That is of course the boughs are to the ground and offer cover for them. Also are there any lone taller trees you can stick a stand in? I also remember finding the scrapes on trails thru these areas and would sit near them but that can be tough. The best place might be on the edges of these stands as they usually don't offer good food sources and the bucks will come out/go in in the morning /late evening.
