The picture above was taken in Cross River State which is south of Jos and borders the country of Cameroon. This past weekend I spent 5 days up in the mountains and even did a little hiking. The weather on the mountain is cold and it rains there often. Above is a picture of an older man who was out returning from his farm and making his way back home. In the picture you can see some green hillsides and potential rain on the horizon. While the rest of Nigeria is begging for rain this particular state is enjoying cool weather and wet ground. For 5 days I felt like I was back in Papua New Guinea enjoying cool weather and delicious bananas. I was very happy to see this side of Nigeria. I hope this gives you a better look into this wonderful country.
Note: the picture is not "foggy", rather, it was taken in a cloud.
