Sorry Chris - I do think a lot of people might like to get to see Teotihuacan and the confusion about Hoy No Circula could prevent them from making the effort.
This being an RV forum we are talking to RVers about RVing. So we want a way to take our houses with us and go somewhere to spend a bit of time in our RVs. Taxis and hotels are never the first choice for any RVers I know.
As far as I am concerned going to Teotihuacan means going to see Mina. There are ways to do it.
The idea that a caravan with any number of RVs cannot get there because there may be people with the wrong license plate on the wrong day means maybe whole caravan companies may avoid the whole idea of going to Teotihuacan. To me that is a terrible shame.
I found all the pertinent information and posted my thoughts based on that information. People disagree with that information but do not post where they get their information from. I posted more and more detailed information in an effort to get the point across to those who do not seem to get it. Sorry - I am well aware it is way way way too much.
People out there may not get a chance to see this amazing place due to misinformation. I have tried to correct the misinformation and to post the facts so people will know it is possible to visit Teotihuacan even with the Hoy No Circula. And if people want they can also visit Mexico City from Teotihuacan while leaving their RV in a safe place while they travel to Mexico City for a couple days - or more.
I posted more than anyone will ever need to know because people dispute the facts and what is on the website of the government agency in charge of the Hoy No Circula - what other authority could possibly be a better source of the rules than the agency in charge and making and enforcing the rules?
I do not want people interested in visiting Mexico or any part of Mexico to NOT go because they were misinformed. I always try to correct misinformation and provide facts and specify clearly where those facts come from - as I am sure you know well.
So to everyone out there - go to Teotihuacan. If you can go on the days your license allows then you can take the route you might prefer. But if you cannot there are options. As the Hoy No Circula website specifies Teotihuacan is NOT in the Hoy No Circula. I spoke with Mina about this years ago when we were there and we verified it with the area authorities - well before we knew there was a Hoy No Circula website.
If Teotihuacan is in the Hoy No Circula or if the entire State of Mexico is in the Hoy No Circula I cannot find any factual information anywhere that states any such thing.
