I read it too, Mo....but I have to take our herd dynamics into effect and apply that to everthing I hear and read.
I used a grunt call in PA and it worked great.
Here......I "think" I hit it once, last year, in 48 sits.
I never took my can call to stand.
If your herd dynamics are more balanced......I'm sure it's a great tool in your woodshed. Here......I think it only screams (wow.....there's ANOTHER doe over there....to the other DOES!

).
