whats your secret? with the crows?
A FoxPro caller w/remote and angry crows. I setup 200yds away (17AH zero), and rotate between "crow party", "crow fight", and "injured crow" (mainly the second two once a few are on the ground/hung in the brush).
Camo'ed up and mouth calls usually would result in a third of what the FoxPro does for me. Results vary...mainly on how aggresive the crows are.
It sort of feels like cheating...
