Below the bridge at Cooper's Cave the Hudson forces itself through rock, and in March that gorge runs loud enough to hear from Glen Street. Mc Dougall Landscape & Lawn works the hinge of that season from both sides — plowing and clearing snow while it lasts, then mowing, trimming, edging and the spring cleanup that finds the lawn again underneath. Grass here comes back gray and matted and needs coaxing; a thorough raking in April largely decides how a yard looks in July. Autumn reverses the whole thing, leaves down off the maples along Sherman Avenue and out of the beds before the ground goes hard. Two opposite seasons, one address, handled by people who see it every month of the year.
