Hi Ed!
Thank you very much for your time to answer!
That is the picture I have seen too, that the best schools is in the Sao Paulo area.But I have seen that I may be able to take my IR-rating at the aeroclube in Brasilia (Luziānia).
And I agree with you, I will be heading to Brazil in de beginning of November to do exactly what you said, go around and se what the places has to offer!
Again, thank you for your time!
Abracos
