The newer challenges from The Conqueror have added – to the emailed postcards and street view maps – places of interest.
As you pass one in the map, more content is revealed in the app. Whereas the postcards have an image and then paragraphs of context – truly like a letter from the road – the sites of interest have a little text and lots of visual content. Always some photos, often a video.
It’s a nice add. But you do need the app – and of course to have joined a challenge that includes the capability- to access this set of features.
