LEISURE ACTIVITIES : Leisure activities can range from dropping out of a helicopter onto the top of a mountain to snowboarding on newly fallen snow to read- ing a book, from experiencing virtual reality in your own home to sign- ing on for a future space voyage. Your interests can be satisfied with thousands of people, as, for example, running in the New York City marathon or attending the millennium celebrations, or alone, walking on the beach. A vacation can be well planned, like a tour. It can also be spontaneous, as many who followed Horatio Alger's advice of over a century ago found out: "Go West, young man, go West." In addition to this already overwhelming array of choices, technology is allowing for the growth of heretofore unheard-of activities. Snowboarding, X-tremesports, inexpensive air travel, and the Internet are all products of technological advances that have affected the leisure and recreation segment of the hotel and lodging industry.
