One of my biggest pet peeves when camping is getting stuck near that neighbor that stays up all night by the fire, while they drink and talk loud and laugh way too loud all night.
But last year we were at a Provincial Park on Lake Huron and there was a group a few sites over, it appeared to be a father, his teenaged daughter and a couple of her friends. One of them had brought a guitar and the girls played and sang all night by the fire. It was one of the most relaxing evenings, listening to their music gently carry all thru the campground.
