Jorge, I know you can help but I thought this would be a good general question too...
I am travelling to Mexico City in two weeks for three days of business. I am trying to decide what to take. I've been many times, always with a little Leica, and the street photography seems to be unparalleled. But now I am using larger formats. Is it worth it or safe enought to take a 4x5 if I won't be leaving the city? I have an AS monorail, so it's pretty conspicuous.
