It’s time to peep some leaves! The eagerly awaited color change has officially begun, signaling the start of sweater weather. And what would fall look like without cider pressing, wagon tours and kiddos perched atop tractors? The Harvest Festival at Merck Forest & Farmland Center offers all of the above, plus tree-to-timber demonstrations that draw on Merck’s 70-year history in forest management and add a sprinkling of biodiversity and sustainability to the ushering-in of all things autumn. Trees are the reason for the season, so it’s only fitting that they're at the root of this festival.
