The hills around Far Hills hold fog in their hollows until the sun climbs high enough to burn it off. Crestview Tree And Landscape Service Inc. mows on that rising ground — lawns that roll instead of lying flat, fence lines to trim along, slopes that ask for a careful pass. Grass grows well up here in Somerset County, and a good cut shows the contour of the land the way a good haircut shows a head. Through the season it is mowing, trimming, edging and cleanups, right up to the first hard frost. Standing at the top of a finished lawn and looking down the length of it is worth the climb.
