Taking Feri to Brazil

I'm planning to visit Brazil (by way of Chicago) in October/November 2014 in order to meet my distance students there and initiate a couple of people into Feri. Airfare is beyond my means, so i'm asking all my present and former students, and anyone else who's willing, to donate $10 or $20 to help me defray the costs of this journey, including transportation within the country.
