I recently bought Fourth Bear from Audible, which invariably lead me to Thursday's books. Wonderful stuff, I own several!
I convinced my bride, Bonnie (she's Scottish, to boot!) to take a Thursday Next book deep into Scott Hollow, which is a famous and very limited access 28+ mile cave system in West Virginia. How limited? The owner has built a house around the cave entrance. Attached is a picture of Bonnie reading "The Eyre Affair" at one of the cave's most beautiful sites - the Double Waterfall on the Mystic River. It takes several hours of serious caving to get to this point, so the site is not for the faint of heart.
PS - this isn't "dangerous stuff", as her feet are about a meter from the floor. She'd get muddy and wet if she slipped, at best. And she ALWAYS wears a helmet and pads!
