Just got back from that area. Temp hit 6 one morning, 2-3 inches of snow, ducks and geese were heading south in droves - fun to watch.
My observation - pretty unscientific - most beans picked, very little corn. Talked to farmer friends and they said part of the problem is the moisture in the corn, not just wet ground. Saw very little corn being harvested even on higher, drier ground.
Hunting was the toughest I've seen in decades. Some of my usual sweet spots held no birds. Most of our success was late afternoon I think as birds were leaving the corn.
Motels usually full were almost empty, no lines at restaurants, has to be tough on their economy. I hate rubber boots but its all I got to wear. Glad I didn't put the hip boots on but to cross some of the ditches would have needed them. Friends that have lived there 50 years think its the wettest fall they've seen. Did a lot of backing the truck up because of flooded roads.
Good news is the birds we found held pretty well. Strangely some days we did not see a hen only roosters, maybe 80% of the birds we flushed were roosters. All our roosters were mature birds, none I would call late hatch.
Looking forward to going back when more corn is picked.
