Thanks sirs. Frie I'm doing just fine It was an amaizing experience, so much to see, such an extremely diverse nature and culture.
Besides Monterrey I visited Cuatro Cienegas, Guadalajara, Guanajuato, Puerta Vallarta, Sayulita, Punta de Mita, Acapulco, Puerto Escondido, Mazunte, San Augustinillo, San Cristobal de las Casas, Palenque, and some other places that I can't remember right now. There would still be a lot more to see so I would really like to return some day.
Never go to the main turist hell beaches like Cancun since they don't represent Mexico. Puerta Vallarta was one of the but I didn't stay there too long.
