Late in May the water at Pentucket Pond goes still enough to hold the whole treeline upside down, and everything on shore is growing at once.

The old houses along Elm Street sit close to the road, so that narrow strip between sidewalk and front door is the entire first impression, and it gets cut and edged like it matters. It does.
