I forgot to buy an extra film roll, so I was walking around during the guided walk in Tavira and being really selective about what to take photos of. When I finally came a cross a shop that sold film, I realized that we had walked through the most interesting part of town, including one of the most abundant gardens. And you know how much I love gardens!
Lesson to be learned: there is no such thing as too many rolls of film when you shoot analog.
