We got to Chetumal last night, we will head up the coast to Akumal tomorrow. The trip across Mexico City went pretty well. The fabled Viaducto route exists, we found it, but we couldn't use it as double axle vehicles are not allowed. We managed to parallel it on allowable streets and then get back over to the Puebla highway. The main problem was tons of construction on the road to Puebla that sent us wandering off into neighborhoods along with dozens of huge trucks and buses. That took a very long time.

More later, I'm on a very bad wireless connection here.
