This place is the Rock Springs Campground in Denver, NC. To the locals that attend annual events here, the place is just known as 'Camp Meeting'. That's my grandmother taking a stroll around the grounds ... the place that she met my grandfather.
This place has traces back to 1794 but was officially organized as the Rock Springs Campground in 1830. The buildings in the backgrounds are called 'tents'. One such tent was constructed by my great grandfather when he was a young man and the the tent reamains in the family today.
An excerpt from denvernc.com/rockspringscamp states, 'When the land that is now North Carolina was first being settled the population was spread out over a large area and churches were few and far between. Families and individuals throughout the area would travel to camp together and meet for worship and fellowship. These camp meetings developed into annual events and were held by the Presbyterians, Baptists, Reformed, Protestants and Methodists. Since those early days these camp meetings have all been discontinued except one, the celebrated Rock Spring Camp Meeting of the Methodists in east Lincoln County, North Carolina.'
