The Erie Canal draws a slow green line through Sweden, and the silver maples along it have grown heavier every season since the towpath was mule track. Lusk Tree Service keeps that weight honest — deadwood out, over-extended leaders shortened, the split trunk taken down before it takes down a garage. October is when the work shows itself: wind off the flat farmland north of Brockport finds every weak union, and the Salmon Creek yards fill with brush that has to be gone by the weekend. Removals happen in tight village lots where the fence, the wires and the hedge each want their space respected. The reward is plain — a tidy crown against a low autumn sky, and a lawn you'd never guess had a bucket truck on it.
