doetrain - I'm in southern Indiana (Gibson County) and I am having the exact same problem. I have heard maybe 4 or 5 gobbles total, in the last 14 days. Talked with a bunch of the guys last night in the chat room (JW!, J76, springspur, x-mountie, Ridge Runner, among others) and here are some of the pointers they gave me. First and foremost, try 2 locate where ur hens are feeding and/or nesting. The toms will be with them and after the hens nest, if u are there, u are in a prime location to intercept a gobbler. An ambush may be your best bet at this point, because they're not being vocal and chances are they're call-shy by now, so calling them in to your location is unlikely. Another suggestion was to find small pockets of woods and tree-lines within a field. Many have had some luck with those. You could try trolling (walking and trying a locator call about every couple hundred yards, but I'm not doing that simply because I don't think they'll call back. You may get lucky though trying something like that. The upside to that, is you cover a lot of ground, your calls will mimmick the vocals of a moving hen and you may flush a tom out that way. Your best chance is to be where they roost, nest or feed. I'm sitting in my blind right now (on my blackberry, LOL) and trying a totally new area. We have a strong wind from the south, so I found a little pocket of woods in a valley that fortunately blocks the majority of the wind. I have hens feeding all around me, I was lucky enough to see a tom with one of the feeding hens to my south. I'm hoping that I'm set up in her nesting area and she'll lead him right to me. I've heard a couple hens yelping to the East of me - 4 quiet yelps - so I'm echoing that on my slate call about every 20 minutes or so. It's a gamble, but I'm hoping I chose the right spot 2day. It's all about location, if you know where the turkeys are going to be then all you have to do is sit and wait for them. Easier said than done - I've been 12 hours in the blind trying every possible technique and location and I've had no luck whatsoever. Unfortunately, part of it is just that - LUCK!!! I don't know if this helps you or not - but I'm in the same boat as you guys, so I thought I'd pass along the advice I was given. Best of luck to you - I hope to see a post with some dead turkeys on it from you!!!
