Not nearly as cool but the houses/shops along the main road up the hill in Jim Thorpe have the creek/rapids running under their basements out to the lehigh river. some have windows to view.
WOW!!!
There was a tattoo shop by the old jail that had a glass floor in the bathroom and you could see this creek. I always wanted to explore this creek underground. Anyone up for an underground adventure??
