Out past Tatnuck the city loosens into brook and ledge, and June evenings hold their light long enough to finish one more yard. Peter's Mowing keeps to that hour, when the heat lets go and the cut lines come up bright across a lawn. Worcester ground is glacial ground — stone under the sod, roots under the stone — so a good mowing pattern is earned rather than assumed. The trimmer takes the fence lines and the mailbox posts, and the edge along the front walk gets cut until it reads like a drawn line. Grass here runs fast in a wet spring and turns stubborn by August, and both get the same attention.
