Americans making summer travel plans will likely skip some of the nation’s most popular landmarks according to a Greyhound survey. The poll of 1,000 nationally representative American adults, explored how often they travel, where they go and how they get there.

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 the nation’s capitol has been seen by less than one-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).
