Welcome back Captian! haven't seen you for a while. My suggestion although not pratical would be a tree stand overlooking the plot. If you're close enought I'd like to play vigilante.

The crows you can probably scare off with an owl decoy. I can't think of anything to scare off a hungary pig that wouldn't scare off deer.

***Forget the owl decoy. I read it as crows not cows. I thing a tree stand is in order.***
