When I look at property for sell in the area of Holly's abduction I see many large plots that list numerous small caves and springs.
They are so common there.
Interesting just to google Decatur County or Tennessee River real estate.
Also as far as the perp being a soldier who returned to Ft. Campbell, it really isn't much of a stretch for him to end up on the TN river or any of it's adjoining areas.
JMO and will be back tomorrow still praying for an alive Holly Bobo!!!!
