"Brazil is a huge country." Wow, you don't say, and there was me thinking Brazil was about the same size as Belgium. Thanks for putting me in the picture.
"... the country is too big to be covered in one book." So, would you prefer a guide book for each state or even each city? There's an economically attractive proposition for the publishers; you should take this fantastic idea to them, you would make them "millions."
I have a suggestion for you before you consider posting your next musing or words of wisdom; If you can't find anything sensible to say, then say nothing.
