Derry, Ferry, and Library streets is a park that displays large toy soldiers and other decorations at Christmas time. Hudson Center, historically Hudson's other town center, is located at the five-way intersection of Central Street (Route 111), Greeley Street, Kimball Hill Road, and Windham Road near the geographic center of the town. The two most important landmarks of Hudson Center have been lost to history. Benson's Wild Animal Farm, a zoo and amusement park, was closed in the late 1980s due to mounting financial losses. At one time there was a railway that passed through the Center, taking passengers all the way from the Boston area to Benson's. A rail depot stand remained on nearby Greeley Street through the 1970s. The acreage of Benson's Wild Animal Farm was purchased by the town and is now a park for passive recreation. The other landmark, Thompson's Market, closed in 2002 when Mr. Thompson decided to sell his store and retire to Florida. The structure still remains, but it was remodeled and reopened as a 7-Eleven convenience store. The original Thompson's Market is also nearby, a small building on Kimball Hill Road now home to a popular sandwich shop. Greeley Field, a popular park located in Hudson Center, contains a playground, Little League baseball diamond, and basketball courts, where pick-up games still occur frequently. A Revolutionary War-era cemetery and an old school house (now housing) on Kimball Hill Road are located nearby.
