Places I know or places of which I've heard? There are places I have heard of that are better and worse than the best and worst places I know.
The best place I know is in East Tennessee, at the end of a short hiking trail. It is called Margerette Falls. This should not be confused with Marguerite Falls, which is something totally different.
The worst place I know is my workplace. I don't wanna go back there. But if I stop going there and working, they stop paying me.
