Have you ever gone to Mexico, what is it like?

I want to go to Mexico, like a rural part of Mexico and see what its like for some reason. Like what the people are like and what they do. Have you ever driven through Mexico or anything? I've only been to Tijuana... I have an Aunt whose married to a Mexican man in Rosarito, but I have no idea where that is. I want to go to Mexico!? Is it really dangerous though??
