I'd say stick to central flyway (KS or OK) rather than Mississippi flyway.

Seems most of the big outfitters are moving that way. I'm still stuck in the historic southern Mississippi flyway but the birds just aren't coming this far south anymore.

If MO is still on list, I'd try to get a spot at Habitats Flats with Tony vandemore. They have built it right by most accounts. You better have some money in the bank if you want to go on that hunt.
