Great pictures of Santiago! Brings back memories - I was last there in 2008 when I spent around a month in the city (2 months total in Chile) during grad school. It's not the most exciting city in Latin America, certainly, but it has some nice things to offer, and it's an enjoyable place to spend some time.
Did you go to Valparaíso? (Or is that going to be in the next installment?)
