Chase came in 1886 to oversee its development as a resort town and laid the ground work. He participated in establishing its street plan, water sports carnival, ice toboggan slide, and trail system. He helped organize the borough, design its water and sewer works, electrify it, and plot the bottom of the lake. He helped design the narrow gauge railroad that once connected it to Sonestown. Among the five large resort hotels serving the area from the 1880s to 1940s was the Forest Inn, opened in 1902. Its guests included General George C. Marshall and theater directorAlvina Krause. Lucy McCammon and Miss Krause leased the Inn's Eagles Mere Playhouse in 1945 and ran it for twenty years; it featured performers such as Patricia Neal, Jimmy Gheen, Charlton Heston, Jennifer Jones, Paula Prentiss, and Richard Benjamin. That troupe is gone, but in 1993 the David A. Dewire Community Center was the site of a nationally recognized summer drama workshop.
