I have to say, the Portuguese are the friendliest people I've ever encountered. Full disclosure, I've only visited twice, both times
back in the mid-70's, so I know things change. For example, when we visited the Algarve (southern coastal region), Albufeira was
nothing more the a fishing village. Now, it's a "destination" on the Algarve. But I'm sure the people are still friendly. Now that I
live in Arizona, Portugal seems like the other end of the world ('cuz we used to live in Philly...just a short hop across the pond).
Still, I'm giving serious thought to returning, this time with RS.
