“I originally called them petroglyphs. But these are marks left by this sport, no one will come find years from now. The marks have a brief life, since they’re painted over each season. Some marks are distinct, others similar, but each has a uniqueness and they only happen once. They’re more like baseball fingerprints. And just like fingerprints are wiped away from a window, each season paints over the marks and covers these baseball prints.”

I love that idea: Baseball fingerprints.
