Going to Mexico?

Well, our youth group is officially looking into the possibility of going to Mexico for a Missions trip. And I'm excited. I find myself thinking about Mexico a lot (long before this trip was planned). I often wonder if God is calling me back there, or if I'm just missing it because it was such a good time in my life. I know that when I lived down there, there were many times that I felt way out of my comfort zone, and struggled with different aspects of the culture and the things I was doing. But at the same time I really enjoyed it. So the question becomes, am I romanticizing my time down there, remembering it as better than it really was, or is God actually possibly calling me back there some day. I don't have a clue at this point. All I know is that I'm really stoked about the possibility of getting to go back for a while. Now I just have to wait a year. Sigh.
