I´m here! At the free Internet area of the actually surprisingly wonderful (thus far) Hostel Amigo. They even offer free pick up from the airport, which saves a nice $20.
And saving money is really a good thing right now, because I somehow managed to lose track of the envelope containing all the USD cash I had withdrawn for the trip. Horrifying. I cannot imagine where it is or how it vanished. I refuse to be overly saddened though, given that there´s nothing I can do about it now.
So I´m heading out while there´s still light to see the historic zocalo (square/plaza) nearby.
PS: The “DF” stands for federal district, i.e., the metropolitan area.
