Sounding the Reef
In the thick woods of nearby Chicamauga National Battlefield, his cousin, Glen, slides down into a limestone cave to hide the gold piece for Brad to find. In the dark, he bends to place the coin on the faint glow of foxfire from a piece of rotting wood. Before he can stand, he gets dizzy and faints. When they wake up, they discover they are on a steamboat in 1854.
