got back (or, I am actually in Sao Paolo, but off the island). had a blast, but I don't have the fucking cable to post pictures, so when I get home next week I will.
spent 48 hours, which is all anybody really needs. rented a quad, saw pretty much every corner of the island. took maybe 500 pictures. really fantastic. I don't know if I would have gone if I had to pay for the trip to Chile, but it was really great.
