After 5 days of entire nature I turned back to the other extrem ...city life in the capital of Bahia: Salvador.
Here I did my first Couchsurfing experience in Brazil. Without knowing before, my host Mauricio, studied like me in Ilmenau, and he and his family hosting me so nice - starting from picking me up at he early morning from the bus station, showing me the town and give me a cosy home for 4days. Serving the topics, of course auricio played in a Samba band, where he took me on a Open Bar - Pary the first night where they played. As you can imagine lots of alcohol and samba and dancing.
Next day, Sunday, I went in the brazilian way to the town beach "Ribeira" where many, many people pass their sundays...sitting together in chairs under a sunshade, drinking chilled beer and eating fried fish, grilled shashlik or cheese, o tipical bahian fastfood like Aracaju or Araba, underlined with extrem loud party music by parked cars aside with open trunk and huge boxes which treat with ultrasound the whole area. They doesn´t care the signs every 20mtr on the street...Loud music forbidden. Brazilians get bored at lonely beaches...for them a perfect free day at beach has to be in company and always partying. In the evening I met with Isabel, a spnish girl of my hostel in the Chapada, and we went of one of this incredible lots of concierts which always take place in Salvador. We saw for free a regional rock band, Casca Dura ...and we enjoyed it pretty much.
Next day Claudio and a friend of him (I got him know on my trekking trip as well) did also a really cool sightseeing tour with me through Salvador. We had lunch at a really cool beach restaurant with view on a light house and at Shrimps in Coconut cream...yummy...and drank Malzbier, they call it "Mausebier" here. But different from Germany it contains alcohol and isn´t that sweet. Lechu, perhaps you like more that version ;).
And the last day in Salvador I finished with Mauricio in a quiet nice Modern Art Museum at the seaside, having a ice cafe and watching the sunset, before I took my 15hrs bus to Porto de Galinhas, near Recife, where I spend my Christmas time. 
So again, summarising, I survided Salvador...any one robbed me or something else. I felt pretty save and contrariwise the Brazilian are so friendly and hospitable...I love them and we should learn a lot from them being more open to other cutures.
