Why I don't drive real late at night in Mexico

I only drive after 9 or so only if I really have to because you never know what you may find on the road.
Usually you will find cows more on the road than horses. A friend who drives down Baja to La Paz says it is not uncommon to find cows laying on the asphalt on the middle of the road at night because of the heat of the pavement.....
