Grayville sits on the Wabash at the far southeast corner of Illinois, where river fog settles into the bottoms on a summer morning and the sycamores show white along the bank. K&N Lawn Service mows through those long green months, cutting, trimming around porches and posts, edging the walks, and clearing the clippings before leaving a place. River-country summers are humid and generous, and grass here can put on a week of growth in about three days. Keeping the schedule is what makes the difference between a yard that looks cut and a yard that looks caught up with. The mowing covers Grayville and reaches out toward Carmi, Crossville and Albion.
