单选题 Once upon a time all you needed for a camping trip was a sleeping bag, a compass and some common sense. Now, according to my local sporting goods retailer, a lot more should be added. However, outdoor travel has become such a trend that urban people find themselves with some upscale retailers to address their every desire.
"Eco" and "adventure" are the latest fashionable words in destination travel; those in the industry know they can make serious cash off all the consumers. These are consumers who get outdoors not for nature"s sake, but to work out simply for a splendid cocktail party.
As a result of high-end demand, the great outdoors is becoming less affordable and accessible for ordinary people. Our national parks used to be vast acres of wilderness where people could go and enjoy nature, for free. But over the past 100 years, the government has been slowly selling or leasing off public lands for profit, and our current president is continuing the trend. Large ski resorts have swallowed up plenty of wilderness and small towns in the West by attracting more high-end businesses. Nature is now a commodity that can be repackaged and sold to the wealthy developers. As for the small amount of public land left, well, try to remember the last time you camped at a state park for free.
The Joneses and everyone trying to keep up with them want a piece of the outdoors, but only with creature comforts included. The rest of us are being slowly priced out of nature. Pretty soon my tent and sleeping pack will be out of date; since camping will mean a luxury yurt with skylights for star-gazing. If this is what signifies experiencing nature in the new millennium, then Thoreau must be rolling in his grave.
