Hello ienjoythis. I really do not know. I tend to lean with theluckywriter. The experience I have is mainly with friends who children traveled the last 5 years or so. Sadly the countries they shared they liked the most are in economic and political upheaval (for a word) today like Turkey, Greece, and neighboring countries.
Personally I would like to see the areas for the writing's of Homer like Crete and Greece. Next, would be Scandinavian countries with the Poetic Edda in mind. Finally, would be the UK leaning more toward Scotland and northern England. Again, literature being a theme of sorts.
I would like to share first a thought that came to mind is all half dozen or more I am thinking of cell or smart phones stolen. All of them. That to me is scary. Scary to the point of I speculate any physical harm is of doubt most likely. Yet, what is on those cell and smart phones? Ponder . . . There is personal, family, and some cases school stuff on those. Maybe a temporary one for the trip?
Having viewed your growing hub portfolio, I tend to think the traveler is close to home as a metaphor. My words are only words. If the heart is with altruistic endeavors then I say ponder. If seeking what Mark Twain recommends with his writing from Innocents Abroad,
“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.”
“Twenty years from now you will be more disappointed by the things you didn’t do than by the ones you did do. So throw off the bowlines, sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.”
~ Mark Twain
Well, ponder purpose with purposeful, next and always - who, where, when, what, why, how, and how much of stuff (Authoring this and that?), and consider opportunity with opportune . . .
