A. Buses on the road.
B. Films on television.

In the United States, it’s the season of swimming pools, barbeques (户外烤肉), camping and road trips. 　　Road trip vacations where the car journey is part of the fun are especially popular with college students, who like to explore the country on wheels. These budget trips are ideal for students who often have plenty of free time but little money. 　　"Ever since I went to college, I’ve been traveling around a lot, exploring the country," said Austin Hawkins, a 19-year-old college student from New York. This summer, Hawkins and his friends have spent weekends traveling in New England. 　　The best part about car trips, said Hawkins, is that you can be spontaneous. "On a road trip, if you get interested in things you see along the way you can stop and explore." 　　Matt Roberts, a 20-year-old student from Ohio who drove to Montreal, Canada, agrees. "With road trips you don’t have to plan in advance, you
