I personally think that travel is more of a necessity than a luxury. It’s so cheap and easy to do these days, that it’s good every once in a while to get out and see new places, do new things, and meet new people.
It’s just not healthy, for me anyway, to see the same scenery every day over and over. I love my home state and city, but I relish any chance to get to another state and part of the country.
For that matter, I love getting outside the country too, be it a cruise to the Caribbean, driving into Canada, or flying into Europe.
