Joseph Campau wakes early in Hamtramck — shutters up, bread in the window, the sidewalk busy by seven. Amin's Landscaping works the blocks just off that avenue, where front lawns are small enough to count in strides and every one of them faces the street. Mowing, trimming and edging here are close work: tight turns around porch steps, a clean line where turf meets concrete, clippings swept off the walk before the crew moves on. By midsummer the little squares of green between sidewalk and curb come back thick, and a whole row looks looked-after at once. It is lawn care measured in doorsteps, and the pride is in how sharp a small yard can be made to look.
