You've heard the old saying, "It's like finding a needle in a haystack." Trying to locate a buck hiding in the open can be just as tough. The prairie may look as barren as a desert, but take a hike across a 1,000-acre pasture. Rolling hills, wetland depressions, grassy knolls, eroded draws and weedy fence lines provide adequate cover for a buck. The federal government also helps whitetails hide through the Conservation Reserve Program (CRP), which takes land prone to erosion out of crop production and returns it to grassland. Often the grass is dense enough to conceal a deer. CRP currently involves more than 34 million acres, most of it in the prairie states.
