Most of Grundy County keeps a suburban calendar. Goose Lake keeps a prairie one. If you live off Jugtown Road, Pine Bluff, or one of the section-line blacktops that grid the township, you already know the rhythm has less to do with school bells than with when the marsh freezes, when the cordgrass turns bronze, and when the state locks the gate at the boat ramp.
This is a walk-through of that calendar, written for people who are already here. The claim underneath it: your neighbors in Morris and Coal City live on a village schedule, but your weekends are quietly governed by the waterfowl and upland game seasons that open and close roughly 1,700 acres of prairie and marsh a mile from your driveway.
