In my region, the best way to locate "shooter" bucks during the summer is by locating the soybeans and alfalfa fields and spend evening glassing the bucks using these food sources. It certainly is a very effective way to take inventory of your local buck herd. Another very effective tactic is by setting up trail cams over mineral licks, however this practice is no longer legal here in IL so it's no longer an option for us. Check your local state regs? Good luck and good hunting.
