Drivin' in Mexico City

Well... this will be pretty quick: I just drove for the first time in Mexico City in my girlfriend's mother car. From Viaducto and Cuauhtémoc to Tlalpan on the Periférico's second floor. I was receiving directions via Nextel so I had assistance pretty quick but it was an intense trip nonetheless. I've been here about a week and I've been the navigator in the city with a Guía Roji map on my right hand so I think I know more or less routes, but I know for sure that if you take the wrong exit, it can lead somewhere from where the return could be a difficult find if you don't know the city or if you don't have the city's map in hand, which I do own now. I miss you all, specially my Luna.
