Today I was on a flight over the U.S., and I used my phone to see where I was. Google maps did a spectacularly good job of locating me as a little moving blue dot upon the Earth.
It was fascinating to see lakes and other features on the map at the same time that I could see them with my own eyes out of the window of the plane. I was impressed by how fast this country is, and how much of it is covered in farmland.
And I am reminded once again, lest I should ever forget, that this world is very large, and we humans are extremely small.
