Harrison in April is two towns at once — new glass along the riverfront, old blocks of brick standing behind it — and both of them want the grass to look like somebody is paying attention. Streamline Landscaping works that seam, mowing courtyards and entry strips, trimming the odd corners a mower can't reach, edging walkways, and clearing a winter's worth of grit and leaf litter out of the beds. Every few minutes a PATH train goes by and the ground hums a little; the mowing keeps going. What a well-kept property does in a dense town is give the eye somewhere to rest between the trains and the traffic. That is a real service, and it is built out of real repetition.
