I have had good luck with mineral salt bricks and apple bricks from Mike's (
www.mikeswildlifefeedersandsupplies.com). The other thing you might try would be a deer feeder using a mixture of corn and mineral feed. The other thing you could try is a food plot. Check out Mike's he sells only stuff that he has tested and used himself so he knows all the ends and outs of his products. He has come up with a special seed blend, mineral brick, apple brick, and a protien feed that has worked for me with great results.
