Mark Twain loved to travel and once wrote,  “Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one’s lifetime.” By the way, this is some actual footage of Mark Twain, shot by Thomas Edison in 1909.
