August on the Chartiers Valley flats is thick air and a sky that cannot make up its mind, and the grass along the ballfield edges goes gray-green waiting on rain. Pusateri Lawn Service mows through it anyway — weekly cuts, trimming and edging around every post and hydrant, cleanups when the season finally turns. A dry August rewards a higher blade and a patient hand; cut it too close now and the whole lawn pays for it in September. Carrying a yard through the hard weeks intact is a quieter accomplishment than a spring lawn, and it lasts a good deal longer. Bridgeville and the boroughs nearby are covered from the first cut of the year to the last.
