Is it true the average American never visits other countries during their lifetime?

I don’t know but Americans have a huge, continent wide country we can mostly drive across. We can easily visit oceans, mountains, deserts, plains and virtually any climate without leaving the country. I’ve been to nine or ten foreign countries and 44 of the 50 states. Foreign travel was fun and interesting but little compares with the North Pacific, the Grand Canyon, New England or NYC.
