Touche'.
What is really embarrassing about that is so many of those people are proud of their lack of world knowledge. My next door neighbor, my youngest kids' FIL, my cousin, and my nephew fit in that category. We're working on my cousin and had some success. His lovely London born wife and a couple of their friends, shamed him into getting a passport, then they took him to Jamaica for 3 days. When they got back home, he asked when they could go again.
My neighbor and my kids' FIL admit that they are afraid to travel outside of the US. I tell them that Miami scares me. There's no hope for my nephew as he subscribes to Faux News.
On a different note. Take a gander at my first ever high end Italian bicycle frame.
I scored it at a bicycle swap meet yesterday for twenty bucks.
