So I'm heading to Argentina next week, and whilst there's heaps of advice on SEheaps of advice on SE about taking USD cash and exchanging at the arbolitos for the blue dollar, I was wondering if anyone has any tips/locations/things to look out for when I do this? I've heard you can be ripped off, so as a single female non-Spanish speaking traveler I'm just wanting to be cautious. Especially looking for advice from someone who has traveled to Buenos Aires recently please.
