The failed group selfie

For a week or so, I've been following two young people who plan to travel the world by bicycle for 10 years, on YouTube. Apart from some questionable ideas, there are also useful ideas that are interesting, which is why I look at them. For example, they send postcards with a photo of themselves in action in the area where they are at that moment. Such a postcard says more about their journey than a postcard from a souvenir stall.
I want to copy that idea but there is still a lot to practise.
