For this and the neighborhood_list, if we only want a certain you can use Django's `.values(field)` method with the [queryset](https://docs.djangoproject.com/en/dev/ref/models/querysets/#values) to return only the field you want, convert it to a list, and the call json.dumps on that.

That will also limit the hit on the database for fields we don't want as well (e.g. other Location fields and the boundary field for Neighborhood).
