Are you hunting the big buck, or are you hunting the does back there or both. If hunting the does during early ML, hunt the food sources or main trails. If hunting the big buck during rifle season, find the thickest stuff you can. If hunting the big buck after Xmas, try finding any remaining late scrapes that may still be active. You might even try a bit a grunting here or there. Otherwise concentrate on the edges of where you think he might be bedded and maybe you can catch him at fisrt or last light. Good luck.
