From my experiance, its absolutley amazing how quickly and how big those bucks racks get if you don't shoot them. Let them grow up! the past three years we've let our bucks pass unless they're tru trophies. Its was hard! Now were seeing some true monsters. Let them get to 4 1/2 to 5 1/2 years and you'ff have some monsters. Especially in Iowa!

Good Luck!
