Porto

From Trashwiki

Porto is the second biggest city in Portugal.

amylin saw some older women going through the dumpsters in downtown Porto one late-afternoon. One was prying the lid open and the other was digging stuff out. She didn´t bother to ask them if they were dumpster diving for food, or looking for anything specific. She just walked by.

This was in an area with a lot of dumpsters, though... and two supermarkets: Minipreço and Pingo Doce, as well as a lot of shopping centers around.
