hmmim guessing you never hunted the area......so you have to find out if they actually roost there or not....so id sneak in to hearing distance....100+yds...and try to hear them gobbling on the roost...if you hear them and they are there...head for your blind....set up...call em in...or just sneak in early.....(hour before legal sunrise or so) get in your blind and wait.....if and when you hear them try to call them in......good luck.....the birds may roost there or maybe they just poop there....who knows....but id bet youll beable to hear them in the morning off the roost from your spot even if they dont roost right there.....good luck
