It's cold. Burly cold.
I saw mallards, green wings, wigeon, and goldeneyes in the valley last week. The hunting for geese and ducks is legit if you can find a field to hunt in or if you do the work and find public open water. It sucked this year compared to last year from opening day until freeze up. Still not as many birds as there should be.
But it's cold. I've had days there where I drove an hour only to turn around for fear of frostbite. Don't get stuck, carry chains and a shovel for your vehicle, blankets, food, etc. Even a mile off the road can be too far on some winter days. It's also a lot of post-holing crusty snow to get where you want to go. You've gotta work for it, and just when you bust your hump and do it all right, those local ducks will zero your ass.
