So far, I have conducted a quick survey of people on the bus from Santiago and amoung the youngsters that I've met through my friends in Concepcion (one has been here for 7 months). Almost to a person, when I bring up Robinson Carusoe Island I get an excited response about how unique the flora is there and how important a place it is. Of course, they are right: it has by some estimates the most unique flora in all of planet Earth, with 70% of species endemic. Hearing this articulated by 21 year old teaching students is pretty cool.
Another cool find: super nasturiums growing as weeds alongside the soccer field.
Update: It's Robinson Crusoe Island, not Robinson Carusoe Island.
