The Harris Family moved to Ethipia. Tom, Jon and Joel had the amazing opportunity to go with a team from the Smithsonian to Southern Ethiopia. They would be geologically mapping the terrain and sending out teams of Eye doctors to work with the natives. Here are some pictures. I am guessing Tom took these since he isn't in any of the photos.
