That's not quite true. Mornings are definitely best in Arkansas but you can still shoot plenty of birds in the evening. Besides that you can shoot plenty of migrators as well. As soon as it warms up and you get a south wind birds push, then you get a cold snap and birds reverse migrate. My friend set up a migrator spread in Arkansas last year and averaged 30 birds a day shooting 80% migrators. It's not the constant train of migrators like South Dakota but there's plenty of birds moving.
