I would definitely cover a lot of ground. I just got back from this weekends hunt also. Friday night, me and my buddies all went to different locations trying to roost birds. Between the three of us, we got just one bird to respond. With him as our only option we tried hunting him Saturday morning. He never made a peep off the roost despite us using owl calls, crow, hawk, and a imitation flydown. We tried a few other spots that morning too with no gobbles. So Saturday evening we went up to a new spot I just got permission for. Within a few minutes of the hike in a bird went off. Soon 2 others sounded off too. This was around 7:30. We quickly moved in closer and roosted em. They were gobbling like crazy just like it was the start of the season all over again. We got in close this morning and the woods were absolutely alive with turkey noises. A few soft tree yelps and another imitation flydown and we had a gobbler down before 5:00 am. We worked several other vocal gobblers for the next few hours and just missed bagging another. With all this in mind, I would make covering a lot of ground to find birds in late season a priority. Theres still hot birds out there and quite a few unbreed hens keeping the gobblers in breeding mode. You just got to find the areas where this is going on, other traditionally good hunting areas might have seen most breeding activity finished while other areas it is still goin on. Also, don't be afraid to try to get permission to new spots whenever possible. I obtained permission to 6 new properties just in the month of May. All of them are terrific turkey country and have me stoked for next year allready. And one last locating tip, I generally have slighlty better luck getting them to gobble off the roost with coyote calls then peacock. Instead of a single howl, try to imitate a entire pack with a series of calling. This often works two ways; the sequence of calls might set off a gobbler or it might set off a real pack of coyotes that will then get a gobbler to respond. I have also discovered that pheasant and super loud drawn out cow moo's are great morning locaters. If you can figure out a type of call to imitate those sounds they will also work great and are something the birds havnt heard from other hunters.
