Sweden Street in February is a corridor of banked snow, and every storefront and side street needs a way in by morning. Flat Fee Plowing & Property Services handles that around Caribou — plowing lots and driveways, shoveling entries, sanding the walks that glaze over after a thaw. When the ground finally lets go in May, the same trucks turn to mowing and trimming, keeping lawns tidy through a growing season that runs short and fast up here. It is a straightforward trade, and the reward is straightforward too: an open lot, a swept step, a cut lawn at the end of a long northern day.
