Where in the world?

The town where I will be working is called Masha (or Maasha). It can be found on some maps of Ethiopia. The map connected to this post shows roughly where it is, located between Jima and Gore. I found out yesterday that there is no road directly from Addis Ababa. We will drive from Addis to Metu to Jima, stay the night, and then drive the next day to Masha. The roads are dirt or mud, depending on how much it rains.
