It’s summertime. For many Americans, this is the season to travel. Why? Because school is over and the weather is great. And most of all, they believe they deserve a break. When Americans take a break, they often head for their favorite vacation spot. Throughout their history, Americans have been people on the move. The early immigrants had to travel to get to the New World. Once they arrived, they settled along the East Coast. But they weren’t content to stay here. Explorers and traders journeyed to the unknown western territories. Later, settlers moved west to develop new areas. As a result of this west movement, Americans eventually occupied the whole continent—from the Atlantic to the Pacific. Even today, Americans seem unable to stay put. Research says that the average American moves every five years. Americans are used to traveling. Some people visit friends or relatives in distant states. Some go on low-budget weekend trips and stay in economy motels. Those with more expensive tastes choose luxurious hotels. Camping out in the great outdoors appeals to adventurous types. Some travel in recreational vehicles to camp out in comfort, while others "rough it" by sleeping in tents. Families often plan their trips with the kids in mind. More and more "family-friendly" vacation resorts offer special programs to children.
