March in Delta Charter Township is two seasons arguing: sandhill cranes calling over the wet flats one morning, three inches of heavy snow the next. TNT Outdoor Services MI LLC is built for exactly that argument — plowing and salting while winter still has a say, then mowing, trimming, edging and cleanup the moment it doesn't. The changeover lands on a different date every year, and reading it right is most of the job. Once the ground firms up, the routes turn green and stay that way until the leaves come down. One township, both ends of the weather, handled.
