I am considering moving BA in the next year or so and I have read many of the travel books on Argentina. Argentines especially "portenos" are very proud of their european heritage. I just wanted to know if anyone has seen people of color or know any communities around town. I was looking to be in Buenos Aires or Mar del plata because of its proximity to beaches. I frequently travel alone so I was just wondering if I should be concerned? Also how safe are the streets for women in the evening? Anyone that offer info will be greatly appreciated.
