Carlos was a professional, knowledgeable and patient guide. He drove two of us to the El Rosario Butterfly Sanctuary and provided education regarding the Monarch butterfly migration. He also shared his wisdom regarding local fruits, Mexican community law and the Teotihuacan pyramids and history. He was patient while answering our multiple questions about the Mexican culture. The drive was well planned and pleasant. I can not recommend Carlos highly enough. Thank you Carlos for a grand adventure.
