In this era of 24-7 technology, the increasingly rare luxury of peace and quiet ought to be added to the list of the world’s most precious commodities, right up there with fresh air, clean water, copper, gold and diamonds.

Just ask vacation-goers who can afford to buy a slice of quiet. They’re shelling out cool thousands in order to travel to so-called “black-hole” destinations – places where technology can’t creep in.

So says Travel & Leisure, which predicts: “The greatest luxury of the 21st century will be dropping off the grid. Black-hole resorts will be notable for the total absence of the Internet – even their walls will be impervious to wireless signals.”

The ultimate getaway, these pricey resorts can be found “on mountaintops, in quaint villages, or in sleek urban centers,” according to the travel magazine.

For those willing to splurge less, “glamping” – is becoming another chic way to get away from it all.

What’s glamping? It’s a phrase coined by Mary Jane Butters, owner of Mary Jane’s Farm, which was recently named one of the top five destinations in America to unplug. Visitors to Mary Jane’s Farm can nix the noise of technology through an outdoor vacation experience that combines camping and glamour.

“Unplugging is the new ‘decompressing,’” Butters said in an interview with Enhanced Online News. “And, due to the economy, Americans are turning to camping as an affordable vacation option.”

Of course, for those of us who can’t afford to get away right now, there’s always the option of turning off the cell phone, shutting down the computer, tuning out the television. We call it unplugging.
