According to Google, "The term being gray means fitting into the environment so that an
observer does not see you as anomalous. The phrase infers things such as
avoiding wearing bright clothing or other items that might draw attention to
you, but the concept goes far beyond bright clothing and flashy accessories."
When I researched grey areas, I discovered the collinsdictionary.com
definition of grey nomads, the term for Australian retirees who camper travel
all over the vast expanses of their country.
Moreover, whenever traveling, it helps to key down your image, and melt
into the environment of a city, small town, and it helps when stopping along
the highway for a bite to eat, but the idea of grey mysterious
"hinterlands" European travel, is an adventure that could be
worthwhile, certainly, it's not your usual European destination kind of travel,
and could be a worthy of a thought for those who tire of traveling to what
today is a similar tourist experience, insofar as hotels and restaurants.
Whatever you do, travel is a multi-faceted experience, gray traveling and
grey destinations will add to your memories, something to pull out of your mind
on a snowy winter day or a rainy day, and there you are back to when you were
enjoying the moments.
Happy traveling!
