El Rostro is wild. I spent several hours strolling through this seemingly never ending mass of humanity. There is everything imaginable and in some case the unimaginable to be found there. Leather, trinkets, antiques, books, clothes, shoes, and curios of varied quality to be purchased here. There was plenty of police present, but I was still warned of pickpockets. I did not see any street crime, but I was kindly forewarned by the owner of Hostal Chelo about how to guard my wallet.
