Some observations about this map:

1. It is creepy that Google knows, automatically from my cell phone, where I’ve been for the past 30 days. (Try https://maps.google.com/locationhistory to track yourself.)
2. I have been traveling a lot.
3. This is a great country. We may be running it down a bit. Its people are very divided–including the people I’ve enjoyed meeting over the past month in settings as different from one another as downtown Baltimore and Provo, UT. But it remains magnificent in its natural and architectural beauty and its endless parade of human beings.
