Greyhound has conducted a “Hit the Road” survey, a poll of 1,000 nationally representative American adults, exploring how often they travel, where they go and how they get there.

Americans making summer travel plans will likely skip some of the nation’s most popular landmarks. While it was reported that Americans like to travel regularly for pleasure, with 82 percent taking at least one leisure trip each year, few Americans have visited iconic U.S. landmarks such as Mount Rushmore (19 percent), the Liberty Bell (27 percent) and Niagara Falls (35 percent). Even the Washington Monument in our nation’s capitol has been seen by less than half (42 percent) of Americans.

The survey also found that 37 percent of Americans have been to less than 10 U.S. states in their lifetime. Florida tops the list of the most-visited states (62 percent), followed by California (56 percent) and New York (51 percent).

The survey was conducted online by Kelton Research from March 19 to March 24, 2008. Quotas are set to ensure a reliable and accurate representation of the total population of Americans ages 18 and older.
