Fewer Campers at U.S. National Parks (AP)

AP - Arthur and Mary Varricchio used to pitch a tent when they visited Acadia National Park. These days, they're more likely to get a motel room with air conditioning, clean sheets and a soft pillow. The Varricchios, who are in their 50s, illustrate a growing trend of baby boomers forgoing camping, especially in tents, when they head outdoors.
