We've been in Juba since last Saturday, and we've got one more full day to go. It's been a great, quick introduction to Juba and a few of its residents. The city is swelling with returning refugees and other newcomers.

Some new residents find their way to Gudele, a suburb springing up on Juba's outskirts. Since the war ended in 2005, Juba County is believed to have grown from less than 200,000 people to almost 500,000. Schools are packed with more than 100 students per classroom. River barges arrive several times a month with hundreds of people returning from northern Sudan. We met one couple who arrived nine days ago on a barge. The whole journey took three months and they had a newborn. I can't imagine what that was like.

So far, there is only one paved road in Juba. The rest are busy, dirt roads. Sometimes the dust makes it hard to see what's ahead of you.

These guys were hanging out next to a central park. Whenever I asked people about Juba's future, they said they thought things were going to get better.
