A truck, a trailer, a few machines and a long list of Castle Rock addresses — that is The Working Millennial, moving through the south end of town while the evening light goes long and gold across Crystal Valley. The work is mowing, edging, trimming and seasonal cleanups, taken one yard at a time and finished before the next one starts. Grass up here grows in bursts, quick after a rain and slow through the dry weeks, so the schedule bends toward what the lawns are actually doing. There is a plain pride in ending a day tired with a row of neat yards behind you. Castle Rock, with Sedalia, Larkspur and Castle Pines within reach.
