Allegany keeps time by the university at its edge — bells carry out over the rooftops, students arrive and leave, and the year seems to turn twice as fast for it. Peterson Landscaping, LLC works both of those turns. Through the green half it is mowing, edging and cleanups on village lots and the properties out toward the hills; through the white half it is plowing driveways and lots and shoveling walks clear before anyone needs them. The valley makes for a long mowing season and a serious winter, and the same address gets attention in each. A sharp lawn in July, bare pavement in January, and nothing to worry about in between.
