I visited in 2006 and would love to go again but with talk of default, you have to wonder if that leads to instability.
Went on a tour of San Telmo or La Boca during the day. Guide warned not to come at night. But even in broad daylight, there were soldiers or police with automatic rifles posted in various areas.
When 40% of the population in the metropolitan area is living in poverty, stresses like a default may lead to widespread strife.
That's mainly what I'm wondering about.
