Tourism snapshot: No getting away from high gasoline prices

So I hit the road last weekend with my wife and kids, going on a weekend getaway.

The fiscally-responsible part of me didn't like the idea. Gas prices, as we know, are in the neighborhood of $4 per gallon, but if you take a trip that's half as far away as you originally planned, it's not so bad. And so we journeyed off to Mammoth Cave, the longest cave system (that's known of) in the world. It's near Cave City, Kentucky, and it's the most popular destination in the Bluegrass State. As it should be. It's arguably one of the world's most unique natural wonders.
