Always interesting to go and visit the wikipedia encyclopedia site. Wikipedia, for those who don't know, is a free online encyclopedia that anyone can contribute to and edit. That means that if you see an article and feel you can add more information you sign in and contribute, very democratic. Unsurprisingly the page for current US president, George W Bush, has the disclaimer that "The neutrality of this article is disputed".
There is an entry for Ribeirão Preto, which is interesting and well written though not by a native speaker. I wonder who wrote this entry?
