Horn of Africa: Their People Challenge finished on Thursday, 27 Feb 2014 As we move (roughly) south thru Africa, the next two challenges will cover the following countries:  Djibouti;  Ethiopia;  Somalia; and  Kenya. I am unsure about how many people have been to these countries, so I don't think we'll hit the 35-entry maximum. If we do, then I'll probably add more spaces, so everyone who wants can enter. Entrants are required to (1) vote for each other entry, (2) read the comments (if any) below this challenge, in case I or other entrants post with Rules questions or clarifications, and (3) follow each of the challenge rules...including voting WITHIN THE FIRST SIX DAYS of the challenge.
