I'm living in a town that is either called Ohangwena (O-han-GWEN-a) or Helao Nafidi (hell-A-O nah-FEE-dee). Either way, it's 10 km south of the Angolan border, just off of the B1, one of the major highways.
The town is between the border town of Oshikango (not marked on the map) and the bigger town of Ondangwa. There is a small market here, but to get real food, you need to go to Oshikango. If you need to do any other kind of shopping, the regional capital of Oshakati is the place to go. It also has one of the few places you can get pizza.

I am teaching at a high school called Ponhofi Secondary School. If you have a good internet connection, you can see my photo essay about Ponhofi here. I live on the high school grounds, as do about 10 other teachers and about a third of the students. The school teaches grades 8 to 12 with grade 11 being the biggest.
UPDATED: Here's a satellite photo of our school that I labeled for a Powerpoint presentation. The main gate is at the bottom left corner. My house is the top of the column of four teachers' houses almost in the centre of the picture.
