Kinderkamack Road runs the spine of the Pascack Valley, and the lawns on either side of it change character block by block — deep shaded corner lots, wide sunny fronts, narrow strips that still deserve a straight line. Christensen Landscaping - Bergen County works that whole ribbon out of Hillsdale, mowing, trimming and edging so a property reads finished from the sidewalk. June mornings start with dew silvering the grass and end with the smell of cut green hanging in the humidity. Spring cleanups pull the winter grit out of the beds; fall cleanups take the season back off again. It is ordinary work done exactly, and a well-kept lawn on a Bergen County street says so without a word.
