Wow, thanks for posting this.
I generally shudder at the idea of visiting Africa... merely because of the perceived heat.
But I have long been comfortable with the idea of visiting Eritrea, where the capitol city sits at 2325m elevation, and the 2nd largest city is at 1390m.
I don't realistically envision ever going there, but just to have learned of Eritrea has made me more comfortable about the idea of being in Africa.
