Only if you cross the half way point, just like fishing. All I know is when I used to hunt in GMU121 for deer there was alot of Geese and Ducks everywhere, I mean sick amounts! if nobody hunts this, that's why the amount of birds, maybe it's to far for some of the 425'rs, and it never freezes!!!! I'll have to try it, I'll post successful pics L8TR.
