When going to the Smoky Mountains NP, we notice a sign towards the lake, which also has a nuclear power plant nearby. In summer this place is really popular, people go fishing here, take boat trips, swim and stay the nights in the camping places. It’s February, when we visit, so it’s deserted. We put the money in the envelope, as written in the instructions, tear off the receipt part and go in the park to check out the surroundings.
