Morning in Seward starts with fog lying down in the hollows and burning off the hillsides by nine, leaving pasture, hedgerow and dooryard all shining wet. Oakhill Landscaping works those Schoharie County properties with mowing, trimming, edging and spring and fall cleanups, on ground that rolls a great deal more than it lies flat. Hill lawns are their own puzzle — banks, ditches, odd corners where a farm lane used to run. Cutting one evenly, holding its edges, blowing the clippings off the walk before leaving: that takes knowing the place. Between Seward and Cobleskill the summer is short and green and well worth keeping up with.
