Our love for subterranean spaces is something we discovered only within the last year. It began with our spelunking trip in Kentucky’s Mammoth Cave where we learned there are better ways to experience the underworld than along paved paths. There’s just something unnatural about the aluminum handrails and colored ceiling lights that are the hallmark of developed cave tours. Far better, in our view, to turn on a headlamp and squeeze into pitch black sections few other people get to see.
