Since you're limited for time but goin to be there a few days early I would suggest find yourself a high vantage point where you'll be able to hear over the most area.Be there before sunup and listen for gobbles.Once you've located the roostin area,sit tight and try to determin which way the birds are movin.around midday ease into the roostin area and try to get a lay of the land.Concentrate in the direction the gobbler went.Try to find a setup sight as close to the roost as you can but not so close that you'll bump the bird off the roost.If you can go to you're listenin point the next mornin and listen to see if the bird is reactin the same as the day before.If he is you're all set.Come openin mornin be at your setup site before sunup and let the game begin.Good Luck
