it has taken me over 30+ years to learn the hard way about hunting turkeys and i did not have a computer to utilize the info that is available to us now but here are some tips to store in your mind:know the lay of the land and which direction they normally travel;gobblers like to face east and flydown west of the roost;they rarely come downhill,across creeks,through fences,through thickets or other difficult obstructions.most of these tips have already been mentioned previously.PATIENCE is probably the most important.stop calling when he is within 100yds.,he will find you without the calling when he is this close.lastly,never give up.
