Went out for the opener last weekend in NW Kansas. 10 in the group (2 12yr old girls on their first hunt) hunted til 2 on sat and sun and shot 37 both days. almost none of the birds held tight in the heat. plus most of the corn and milo was still standing. talked to a couple farmers in the area yesterday and they are getting alot of cutting done this week. headed out again this weekend, and hopefully the cold weather keeps them a little tighter in cover.
