Mexico!
I participated in the International Engagement in Mexico program through State during Spring Break of 2011. We worked at a children's shelter in Puebla, Mexico during our stay. Our job was to paint the nursery for the younger children, as well as to interact with the older kids to help them form healthy relationships and learn to properly engage with others. The children had all been removed from their parents for safety reasons, or abandoned. It was a sad experience, but it was well worth it. It was my first time in Mexico, and I absolutely loved it the culture.
