That's one of the good things about BA, there are no expat enclaves - even Nordelta - and it is relatively easy to integrate if you have a mind to.
Exactly, Nordelta is by no means a yanqui enclave. However, it is a upper middle class enclave. You'll find professionals, small business owners, etc. Most are college educated and almost everyone is well-traveled. Perhaps not as much as most of us expats, but enough to have a vision of what things are like outside Argentina -- enough to know that the place we all live can be administered properly.
Oh, and everyone in Nordelta is plainly aware of the fact that private initiative produces better results than the dysfunctional Argentine government. That's why we chose to live in a private neighborhood, most send their kids to private schools, and we rely on the private security and other services. Nordelta is by no means perfect, but it is a huge improvement over the typical municipality in the conurbano.
After 10 years living and working in a number of Buenos Aires neighborhoods -- Recoleta, Barrio Norte, Palermo, Puerto Madero, Belgrano, Núñez, Chacarita, etc -- I'm ready to settle long-term in Nordelta.
I want to wake-up without the noise of colectivos, cars, motos.
I want to take a walk without having to step over trash, broken sidewalks, dog poop, etc.
I want to step outside and breathe fresh air.
And I want to be able to take a bike ride at any hour of the day or night and not worry about a motochorro.
So there you have it.
Saludos!
