When Seth Long first began experimenting with maple syrup production, he tapped hollow pegs called spiles into individual trees, collected drips of sap in milk jugs, and carried each gallon down the the steep mountainside on foot.

Now, Long rides an open-air buggy up muddy switchbacks to a 500-gallon collection tank from which translucent blue tubes branch out like arteries. There, gallons of sap accumulate from Long’s 270 maple trees before they flow through those tubes 900 feet down the mountain to Long’s grant-funded sugar shack.
