Day 450

Today's walk also happened to be the final leg of my friend Moses Gates's decade-long quest to visit every census tract in New York City. Well, almost every one. If he plays his cards right, he'll never have to see Bronx Tract 001 in person.

Moses is a man of many talents. He's an urban planner, a demography professor, a musician who stores his tenor sax in a laundry basket, and a trespasser extraordinaire. He's been a really important influence in my own exploration of the city. And he's a good writer, too — he recently came out with a rollicking, big-hearted book about his adventures in off-limits places around the globe.
