I'm going back to Asia

This summer, I'm leading an ISP (international service project) trip through my school to South Korea. I had wanted to go to Africa or a Spanish-speaking country, but it seems that Asia and I are bound to each other somehow. I'll be leading a trip at the end of July/beginning of August to teach English to junior high and high school students. I'm not sure if I'm excited about it. I really feel like it's a good experience for the students, but I've been to South Korea and it isn't a place I necessarily wanted to return to. Hopefully it's a great trip and opens the students' minds to the larger world - they tend to be fairly sheltered around here.
