I am a long time Wisconsin turkey hunter........I am finding Toms will spend very little to no time in the fields much at all. I have seen them come full out of strutt and duck or lay down as they hear the sound of any vehicle approaching their location. That goes for hens too.
I have witnessed in other parts of Wisconsin where upon even hearing a vehicle approach they actually run out of the field!
So I changed my hunting tactics.......I stay away from roads as much as possible.....and I hunt woods more than ever.....
Just some food for thought....
