Bolton's hills are round-shouldered drumlins, and the driveways that climb them turn slick the moment the temperature drops. Ramos Landscaping mows those yards all summer, trims tight around posts and plantings, and clears the leaves in the weeks after the apple harvest. Then the plows go on: drives opened top to bottom, walks shoveled, salt laid wherever the slope makes it necessary. Coming back down a cleared hill drive at first light, everything black and passable, is the reason for the whole cold night. Lawn care and snow removal for Bolton, Stow, Lancaster and Harvard.
