There is a week in late October when the mower comes off the trailer for the last time and the plow goes on, and Bill's Lawn Services can feel it in the air along Knoxville Avenue. Summer is mowing, trimming and edging — week after week of staying ahead of grass that a river-valley July pushes hard. Winter is the other half of the same job: plowing drives, shoveling walks, salting the slick spot at the foot of the driveway before anyone goes down on it. Same streets, same houses, a different machine on the hitch. Peoria asks for both if you want to work the whole year, and both get done here.
