After a summer rain in Presque Isle the air smells like wet gravel and cut grass, and every boundary in a yard shows sharper than it did the day before. Fine line lawn care takes the name seriously: the mowing matters, but so does where the grass stops — along the walk, around the mailbox post, at the lip of the drive. The routine is mowing, trimming and edging, week over week, so a lawn never has to be rescued, only kept. Along the old rail bed turned walking trail the wild grass runs where it likes; in a dooryard, the line should be deliberate. That difference is the point, and it is visible from the street.
