The green season at the Straits is short and generous — a few months when the grass comes on fast, the ferries run steady, and the limestone shore holds the light until nearly ten at night. Cedars of Mackinac spends it cutting, edging and trimming the yards of St. Ignace, from harborside lots to cabins set back in the cedar. Working against a short calendar teaches you to be exact, because there is no spare week to waste. The first visits of the year take the winter sand and needle-fall off the turf; the last ones put the yards to bed. In between, a summer of clean lines under a very big sky.
