Hi I have herd a little bit about the red light , green light system customs uses at the Mazatlan airport, can anyone give me a little bit more information on this please? Also whan I bought my Mexican pesos her in Canada (sorry I did it now by the way) I was getting just a little over 8 cents to the Mexican Pesos. What is the exchange rate at the ATM's and Mazatlan banks that I would receive? I have herd that it is as hight as 10 cents to the pesos? Can anyone tell me please. Thanks, Westerncanuck.
