Africa is the only continent I'm afraid to visit by myself. I know that many people are peaceful and happy... but I also know there are a lot of problematic areas with violent gangs. I just won't risk going there, unless I'm with a large group of friends.
Thanks for your post, it was an interesting one.
PS: I've found your post because @macoolette featured you in her entry for The Pay It Forward Contest
It's a difficult continent to travel due to lack of accessible roads in many rural areas, but I guarentee you'll love visiting when you figure out what it is you're looking to see.
I don't doubt you.... but lately I've been travelling alone, so I'll be sticking to European countries. ;-)
Ethiopia is not traveling friendly, in terms of traveling alone with no guide. I wouldn't recommend it personally. I'd say much of Africa is like that, but you can get around to figuring it out. Best of luck and safe travels!
