Mexico

I would like to visit mexico, because i've always wanted to see the aztec buildings. However I don't really know so much about mexico, just some facts. For example, most of the people on mexico are roman catholic, but in the past, before spaniards arrived to mexico, inhabitants workshipped several deities and even use to practice human sacrifices for them...Well, that happened long ago. Also, delicious chocolate is from mexico, peanuts and tomatoes too! If I ever go Mexico I would like to taste their food (and drink some tequila, restraining myself of course haha) and I would like to explore every aztec building possible. I just love them, I'm interested in go and see how they built that enormous cities in the past.
I've heard that in Mexico education is free, I'm not sure. Anyway, I would like to learn about mexican culture, about their traditional crafts and clothing and how they make it. I'm not sure about working and staying longer than a vacation there, first I would like to know this country a bit better.
I forgot to say that their beaches are so awesome, I've chosen a photo from a beach just to show you how incredible they are.
