Scranton formerly had a public school building of its own, which had a three-story section built in 1915. The school closed in 2008; the school district had notified the city government in 2006 so the city could plan for the future of the school. In 2010 the city government acquired the building, paying $1 for it, and converted it into a community center; the city government considered converting the school facility into an apartment block, but it determined it would have required too much money. The city government determined that it could not find a purpose for the 1913 section; therefore its razing occurred in 2012. The current Greene County district, as of 2014, rented the school gymnasium for athletic meetups.

Annual events in Scranton include the Mid-Summer Festival, held in July, and a Christmas celebration.

Every five years the town holds an all school reunion, with the next scheduled for 2020.
