Here are some great pictures of African sunset across the Congo River. The sun sets regularly at 6pm. This sunset followed a heavy rain storm. The picture was taken out of our kitchen window, looking across the Congo River into Brazzaville, in the Republic of Congo. We have a 6pm curfew. I know we are too old for curfew, but the sun sets at 6pm and it gets absolutely dark. 1) the mosquitoes come out mean and hungry. 2) it is not really safe to be on the streets after dark. So, we get home by 6 and watch beautiful sunsets.
