Year Round Grazing in Midwest

I am near Chicago and am wondering if there is anyone out there in the Midwest that has had success with year round grazing? My efforts have allowed for expanded grazing season but I now would like to really make the effort to go to a year round system and am looking for examples and methods.

Both Gabe Brown and Mark Shepard do year-round grazing, even further north. Both with lots of youtubes, and both geniuses.

Slightly more south in Missouri is Greg Judy. The main difference will be winter stocking rates and slaughter ratio. Greg gets a much longer season.

All worth learning from!
