Hard to say. Without more context or specific information about Lydia Tar, it's difficult to determine if it's a completely true story. It could be based on real events but with some embellishments.
A 'tar true story' could be about a small town that was built near a tar pit. In the early days, the people in the town didn't know much about the tar pit. But one day, a young boy fell into the tar pit. Luckily, the townspeople quickly organized a rescue mission. They used ropes and planks to get the boy out safely, and after that, they put up fences around the tar pit to prevent such accidents in the future.
