I believe the primary feature to be aware of when discerning buck bedding areas is cover. Big bucks usually prefer to bed in thick cover/brushy areas. Sounds like the CRP fields in your hunting area might offer the kind of cover a big buck seeks. This time of year...if you scout carefully and do your best to eliminate or at least minimize your scent, then you should be able to find a buck core area(staging area near bedding area) and then you can pick a spot on the edge. That has been my strategy and it has produced some exciting hunts. You will know when you find a core area as it is usually quite loaded with sign! Good luck and always be safe!
