What was the most memorable day of travelling for you?

In 2017, I visited the Italian town where my great-grandparents left over a century ago.  The day started with a chat among a group of elderly locals, one of whom shared my family’s last name, followed by a tour of the town hall while waiting for their birth certificates.  I ended the day with a long hike across a valley to catch the last bus back to the coast.
