Hunt at dawn and dusk, unless you want to hunt at night with lights.
Set-up in cover with a view to open fields and a water source.
Camo from head to toe and a good call (I use Primos).
I find my most successes are when I'm set-up near cattle.
Call soft and infrequent.
Most importantly remain as still as possible.
If you have a small "critter" looking thing to use as a decoy, all the better.
Good luck !!!
