River and creek bottoms can provide some of the best deer hunting I can think of , a buddy of mine hunts practically nowhere else and has some pretty nice heads on his wall . It may be a bit early to pattern the bucks , but that alfalfa field is definitely the key element if the food is still there come Fall . Bucks follow does , and does follow food . Pattern the does instead and find those bedding areas between now and Fall . Doe bedding areas are where those bucks will head for in the rut . There will be more than one , so scout thoroughly . River bottoms also seem to be a magnet for bruiser bucks , so practice low impact scouting and stop at least 2 weeks before hunting the area . Good luck !
