I have sort of the same deal. Just outside the bedding area on one of my spots, they brought in heavy equipment and started putting in a big drainage ditch. They have been there since opening day. The deer didn't head out they just moved a little farther away from the activity. They are still in the same general area. Where the does went is probably where you'll find the buck now. Here in SW IA the bucks are really following the does now. I'd bet he's reluctant to give up the security of an area he knows so well.

THWACK!
