The second half the this collection consists of photos and slides taken by Yeager while traveling in Pennsylvania, New York, and New England, and to a lesser degree Washington, DC and the southern United States. Places photographed in Pennsylvania include Easton, the Canal Museum, Bethlehem, Valley Forge, Hopewell Furnace Village, Ephrata Cloister, the Little League World Series in Williamsport, Delaware Water Gap, and Saylors Lake. Yeager had a particular interest in trains, photographing the American Freedom Train in Bethlehem during the Bicentennial, as well as trains from the Lehigh Valley Railroad, the Delaware, Lackawanna, & Western, the Baltimore & Ohio Railroad, and the Central Railroad Company of New Jersey. The collection also contains good documentation of several World's Fairs, including black & white photographs of the 1941 New York World's Fair, with especially good coverage of the Transportation Exhibit, and color slides of the 1964 New York World's Fair and Expo '67 in Montreal, Canada.
