Toll Gate Creek slips north through Aurora under the bridges and past Del Mar Park, keeping a calendar of its own: cottonwood fluff in June, gold leaves caught in the channel by October, ice in the shallows after that. R & R services LLC keeps its calendar alongside it — mowers and trimmers through the warm months, plows and shovels once the pavement starts to squeak underfoot. Summer evenings are for long straight passes and the crisp border where turf meets concrete. Winter mornings are for the drive opened before anyone has found their keys. Same yards, same hands, two different kinds of quiet.
