Evenings belong to fireflies and thunderheads out here — you can watch a storm assemble itself over the fields west of Winnebago for an hour before it makes up its mind. Perez Green Envy Lawns takes the hours before all that: mowing while the light is still good, trimming the edges tight, cutting a line along the drive, and clearing the yard when spring and fall ask for it. Grass cut just ahead of a rain comes back thicker, and a yard that gets that timing week after week starts to look different from the ones around it. That difference is the whole reward. Winnebago, with Pecatonica, Seward, New Milford and Rockford nearby.
