bw97 there are always many variables that can help answer but just with your info i will try to give what little i know. I would assume that if you are seeing tracks the birds(toms) are there. One thing you said that you see jakes strutting if jakes are srtutting then the gobbs are not gathering yet if you hunt elk you know that the really big boys let the little boys do all the work and then come in at the last minute as the girls are hot and ready. The other thing that I am constantly learning is that mature birds are very woods wise they sem to know when anything is out of place in there world you can call hens and jakes in to a set all day but a old bird will bust the slightest thing and you might never see him. What decoys are you using? during these times that the turkeys are not gobbling to "door slams" you have to be very selective with your calling and very accurate with the sound. And as others suggested be patient certain times of the season you can run and bow and thats really what i like, but the last few years i have been setting longer and the reseults have paid off. Its more fun to bring them in hot and in ten minutes but sometimes sitting for 1-2 hours still isn't enuff. I would bet the gobblers are there be patient use cover everytime you move from set to set if they see you from a couple hundered yards the game is over for that bird if he's smart. try to get out to that area again if nothing is talking in a week if possible good luck let me know.
