Next day did a boat tour of the Grotto - highly recommend, and walked through the old town.
Took the Saturday bus back to Lisboa. Steve and Siggi bugged out before sun up to the airport Sunday morning, meaning I had the day to myself. I took a train to Qeluz/Belas and a taxi to Belas. Found the Bombieros Voluntarios and met a distant relative of Cristina. He directed me to the old Bombieros Voluntarios building, where Cristina's grand-dad was the fire chief years ago. Took some photos.
Left Lisboa Sunday night and arrived home via Perth on Tuesday midday.
To my friends Steve and Siggi thanks. Most of all thanks to Cristina.
Pictues will eventually be added! (later: done!)
