Here's the deal. You are hunting turkey 10 minutes from my house. If you are setting up at the cache creek wildlife area and working south. YOU WILL have lots of competition. If you go across the highway its all private and most of the turkeys are there for you to drool over. BUT as with all hunting, you never know.
N Fork Cache Creek doesn't open for fishing until late April.
If you hunt out by cowboy camp, you will have less competition but i have never seen a turkey out there and its a staging area for equestrian.
I have never hunted out there in either place but as with any public land, if the locals thought it was worth hunting out there we would. Thats one of the reasons why i want you to ditch the decoys and blind. You WILL need to be able to move quickly around the area to set up and not worry about blinds and decoys.
