On summer mornings the Ohio River sends fog up over Metropolis, and for an hour the town is soft-edged and cool before the day turns to real southern-Illinois heat. Father & Son Lawn Care LLC. gets out in that hour — mowing, trimming, edging, blowing the walks off while the grass still carries dew. Down here the growing season runs long and generous, green into late October, so the mowers keep going after most of the state has put equipment away. Cutting well in that heat is mostly discipline: level height, clean lines, walks left bare. The river fog will be back tomorrow, and so will the work.
