If it is like MN, it is all over the place. If you go all the way to SoDak don't be afraid to drive some distance if the first area you intend to hunt is too snowy.
The fields in MN are blown bare, which means all this snow had to go somewhere. Ditches are full as are some public hunting areas. Drive 30 miles and the whole situation can be better or worse.
December has been cold and the snow remained light and fluffy until yesterday. With temps in the upper 30s and low 40s across MN and SoDak the snow became wet.
The snow will be come crunchy when the cold hits Sunday.
Walking in 6-10" of fluffy snow is rather easy compared to breaking through every step and the sound in makes as you traverse across crusty snow.
Pheasants on the other hand will be able to run, run, run on top of the crusted snow.
