I think some of us may be confusing tent meetings with camp meetings, which are two different things. Here in NC, the term "camp meeting" refers to the practice whereby a group of like-minded believers meets at a specific place and stays there together for about a week. There is bible study and fellowship during the day, and an old fashioned singing and preaching service every night. Each denomination that does this has its own specific place for the people to meet and stay, sometimes more than one in different parts of the state. It is mostly Baptists, Church of God, and Methodists who still do this here in NC.
What is usually referred to as a tent meeting or tent revival, is when a traveling evangelist from somewhere else comes to town and sets up a tent, then proceeds to conduct a revival. Usually they stay a week or sometimes two at the most. At least that's how it is in my neck of the woods.
