Trail signs, junctions and the trail itself — not people. A readable sign on a trail earns a point.
Tips for photos
From a phone: Choose photos opens your Photo Library. Pick several, tap Add. Keep location on in the camera so each photo knows where it was taken.
From a Mac: the Photos app sometimes drags small copies. Photos → Settings → iCloud → Download Originals to this Mac, or File → Export → Export N Photos (JPEG, Full Size, Location Information on).
Photos are read within a few minutes. Only where and when they were taken is shared.
