Saturday morning on the shaded streets of Vidalia sounds like mowers starting up one yard at a time. Gaspar lawncare is one of them, working a route of in-town lawns — cut, trim, edge, clear, and on to the next. Under the old oaks and pecans the grass runs thin in patches and thick in the sun, and reading a yard right is half of doing it well. The finish is what people notice: a level cut, a clean line along the walk, the drive swept bare. It is a good way to spend a morning and a better thing to drive past afterward.
