I still do not want to argue with anyone. I have research extensively on the internet about this and have posted links where answers can be found. On the following website which I previously posted they list the 125 munipios in the State of Mexico. Teotihuacan is a municipio. Coacalco is a municipio. On their list and their map that follows they show Coacalco de Berriozabal as number 020 on the map and Teotihuacan as number 092 on the map. This would appear to me that Teotihuacan is not in Coacalco. Perhaps there is another Teotihuacan. I cannot find it. Some use the term San Juan Teotihucan. My maps do not show that name. There is a Teotihuacan de Ariste which is in the municipio of Teotihuacan which is where the pyramids are located. Perhaps you can look at this website to find more of a clarification. I will try to post more maps which may help. It is very difficult to find Coacalco on the map as it is very small. It is sort of purple on the map – Teotihucan is sort of brown – all municipios are numbered on the website and on the map. I continue to try to find facts and to post clearly where I find my facts. Hopefully others will do the research and post the facts and where we can find them as I have always done.

020 Coacalco de Berriozábal
092 Teotihuacán

Another website with a clearer view of the map where both 092 and 020 can be clearly seen

See the following website to find the list of the 125 municipios in Mexico State. The municipios are all numbered and you can find them on the map by number.

Here are the number and named municipios you would have to pass through from the Arco Norte to get to see the pyramids of Teotihuacan. They do not appear on the previous posted list of municipios in the Hoy No Circula.
016 Axapusco
061 Nopaltepec
065 Otumba
075 San Martín de las Pirámides
084 Temascalapa
092 Teotihuacán
If you came from the direction of Queretero from the north to get to Teotihuacan I think you would pass through these two municipios which are on the list of Hoy No Circula. Hopefully this will help to get a more clear picture.
033 Ecatepec de Morelos
081 Tecámac
