With the of dawn of 1960s, Otis Clay observed a growing American interest in camping, and began to expand campsites, adding electric and water hookups for RVs and travel trailers. Otis Clay passed away in 1966, but his sons Robert and John continued to build up the Park to meet this growing demand. They continued to expand on Otis’ vision, adding more campsites, bathhouse facilities, a miniature golf course, playgrounds, waterslides, and large pavilions to host company picnics and family reunions well into the future.
