I couldn't finish the sandwich, and I wanted to do something about it. We all felt bad about not eating the food we had.

Before we went I wasn't sure if I wanted to go into engineering, but now that I went there and spent 36 hours doing design work and I'm still motivated about it, it's obviously something I'm interested in.

It just felt very eerie, mystical, like it wasn't real. I was kind of intimidated, a lot of us didn't know what to do.

I took that as even more important, especially with how the U.S. is often perceived. We did something that will leave a lasting impression, and that made me proud.

All of us lined up on the sides of the road, like a tunnel. We made him cry, then that made us cry. We didn't know if that was the last time we'd ever see him.

The road was insane. We crossed bodies of water -- rivers --12 times.

Everybody knew we were here for a reason, so that's what we were doing.

Within that five years they want to build enough confidence with the them and us that eventually they can send a couple daring doctors to hike up to the people and do medical applications there.

We handed out gifts and care packages, and some of the students went swimming with the kids.

On the way back from a hard work day, we'd be all sweaty and dirty and gross right next to each other, and nobody complained.
