The Franklin Inn is located in Somerset, New Jersey. The inn had its inauspicious beginnings as a small dutch home, but was converted to an inn in the 1920s, when owner John Wycoff anticipated a business opportunity with the impending completion of the Delaware & Raritan Canal. The inn was closed in 1916 due to prohibition.

The inn offers a used bookstore, special events including presentations and workshops, and guided tours. The website offers visitor information and a detailed history of the building.

The Daniel Boone Homestead is a state historic site which preserves a number of historic structures. Daniel Boone's parents first settled the site in 1730 and the region was populated by many diverse people—English, Welsh, Scots-Irish, Germans, Swedes, Huguenots, and Lenape Indians. Daniel was born here in 1734 and spent his first 16 years here before his family migrated to North Carolina. Today the site tells the story of Daniel's youth and the saga of the region's 18th-century settlers by contrasting their lives and cultures. This region left a lasting impact on Daniel Boone's life, and on the history of Pennsylvania.

The site offers a short film, exhibits, tours, educational programs, and occasional recreational and educational programs (including living history events).

The Farmington Historic Plantation, built between 1815 and 1816 as a working hemp plantation, was home to John (1772-1840) and Lucy Fry (1788-1874) Speed. Today, the Federal-style home is furnished to an 1830s appearance, the period of time when the plantation was at its peak prosperity; and the furnishing of the home was largely guided by Speed's 1940 home inventory. The number of slaves on site varied between 45 and 64 during the plantation's operation, while the average state slaveholder owned only 5 individuals. Reconstructed structures on the grounds include the summer kitchen and cook's quarters and a springhouse. The grounds also hold a blacksmith shop, never originally on the plantation. The plantation is relevant to slavery, the Civil War, period politics, gender roles, and John Speed's close friendship with Abraham Lincoln.

The plantation offers period rooms, periodic re-enactments offering living history interactions, educational programming in compliance with state educational standards, quill pen writing, a scavenger hunt, 19th-century games, and cornhusk doll making. The website offers pre-visit information packages for teachers. Educational programs are available to all students, including home school students.
