well...what can I say, I did it. so maybe also could you...Not just kidding about this tip. This horse was really used to humans. Is of course you notice the animal doesnt trust you dont do it. Also quick gestures are not good.
On your way to Igrejinha you can notice the large amount of herding farms there exists by the road. hundreds of cattle heads run free in the fields. These guys here look very suspicious and I bet they want a fight.
everybody knows how tricky can water barages be. Be careful if swiming in the summer. Personaly I wouldnt swim even in the summer not only because of the danger but because I don't like it very much. I prefer beach or swiming pool.
