From the ridge at Prospect Hill the whole west side of the city lies out in late-day gold, and every small green rectangle down there is somebody's work. Zecena Landscaping and Construction INC keeps a good number of them - mowing and trimming straight through the week, edging where grass meets pavement, mulch and bed work, feeding and overseeding when the soil is ready, cleanups at both ends of the year. The crew usually finishes in Warrendale and Banks Square with the sun going flat across Main Street. A lawn cut in that hour looks less mowed than drawn, the lines running clean to the curb. That is the part worth doing well, and it is the part people notice from the driveway.
