nd 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，Pve 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.
