Post pictures, let others guess. Specify your question about the picture, in general we ask "Where is this?" or "What is the name of the place?". You can also ask other things. On the other side, scroll through the posts to see if you can guess the pictures!
Where is this place? (Where can you see this place?)
Question: Where is this? Do you remember anything else on this place? Any conversation or anything interesting for you? And of course, the name of the place ;) BONUS: Who is in the picture?
