Cahokia has been a town since the French set a mission down beside the Mississippi, and something of that old village pace still holds in the shaded streets on a summer morning. Es Juan's Lawn Care and Landscaping works those early hours, when the dew is still on and the mower leaves a darker green behind it. Beyond the cut there is mulch to lay, shrubs to shape, and beds to edge into a clean curve against the lawn. Planting goes in wherever a yard is asking for more than grass. By the time the heat climbs, the block looks tended and the trimmings are already gone.
