Another equally important ritual we endure is thinking about how much cash we should bring just to pay the toll fees. It's a pricey luxury here to use a paved road without potholes or speed bumps (for example, round trip from Mexico City to Acapulco is 1008 pesos ($72)!). Everytime we approach a toll booth, I worry that we don't have enough cash with us, and then my imagination wanders into bad places like Mexican prisons. It's ridiculously expensive, and if you plan to use the toll roads, be ready to hand over your life savings.
All this to say that I've found a lovely website created by the Secretary of Transportation that will not only give you a detailed route of how to get from point A to point B, it also gives you the exact toll fees. This site is the equivalent to Google Maps for Mexico. So no more sweaty, desperate searches in your wallet for cash--you can prepare all your tolls in advance and surprise everyone with your god-like knowledge. Although you can't enter in the exact address of where you want to go, it gives you enough information and then you can ask around for the rest.
And the final ritual is to pray to Montezuma that he won't have his revenge on us as we indulge on edible delights that await us.
