The oak and hickory woods at Black Hawk State Historic Site stand over the Rock River, and the seasons show there a week before they show up in a yard. Outdoor Specialists llc reads the same calendar, mowing, trimming and edging once the ground firms in spring, cleaning up through the leaf-heavy weeks of fall, and hanging plows on the trucks when the valley goes white. Winter work here means driveways and lots opened, walks cleared, salt laid where the low sun never reaches. It is the same properties looked after continuously rather than seasonally. Rock Island and its neighbor towns, kept the whole way around.
