The Minuteman Bikeway runs the old rail bed straight through Arlington, and half the town's back hedges face it — which means those lawns get looked at all summer by everyone on a bicycle. Lawn Boys Landscaping keeps them cut, edged and trimmed from Arlington Center out to the Heights. July here brings growth that will not wait a week, so the schedule holds and the mowers keep moving. Spring is cleanup and a first cut that wakes the whole yard up; late fall is leaves off the grass before frost sets them there. A trim strip of green behind a picket fence is a small thing that makes an entire block feel settled.
