I usually get into a known roosting area way before roost time about 2 hours early... That way there is no chance of spooking the birds... Then I just pick a spot about 75 yards away and just sit tight and lisen... I stay in woods until just before dark and then I owl and check to see were the Gobblers are... It's sucks having to walk a 1/2 mile out of the woods in the dark...
