This story in The New York Times made me miss New York City more than anything has in a very long time.
All over the city, artists have created murals protest racism and police abuse. This critic surveys the murals, and compares them to the Neolithic cave art in the caves of France and Spain.
We saw cave art in Spain (stories here and here, but no pictures), something that I had longed to do ever since I first knew they existed. It was a peak travel experience for me. I love street art, and I love New York, and I love that someone links these things together.
