Unable to answer "What’s the surface here?" – Path – way/921090117 via StreetComplete 57.1:

This part of the trail network only really exists during the winter. During the summer the field is used by birds so people can't walk here.

Unable to answer "What’s the name of this street?" for way/639219794 via StreetComplete 53.3:

This road has no streetsign, or name. It provides access to the fields along it, as well as the small recreation area in the woods. That street is labelled 'Zimmer's Place' but I have never seen a street sign on it so I cannot attest to that.
