Can you get on the field that they're feeding. If so set your self up in the early morning. I always go for the morning hunt. You can catch them off guard, first thing in the morning especially if they come in early and like discusdad said "total concealment is a must". Geese have good eye sight. If you can't get on the field that they're feeding scout for another field. If you can get a field were they feed at night, they will be back in the morning.
