This is a great example. I tried running it myself locally.

The README.md doesn't explain how to create the mongodb indexes, and it doesn't work without them...

Hi frumious.

Sorry that the readme is light in this area. Before loading the data, just start a connection to mongo, and `use geo` `db.ny.ensureIndex({"geo": "2dsphere"})`. And you'll have your index.
