No, don't beware, and yes, you read that right - donkeys.
Donkey's boost Ethiopian literacy (BBC news story)
In Ethiopia, donkey-drawn carts bring children in remote villages books. The Donkey Mobile Library, Ethiopia's first, has another mission as well - the donkeys pulling the carts are part of a campaign to help improve treatment of donkeys. The program's mascot is Queen Helena, an elderly donkey who has been retired and no longer pulls the cart, but still accompanies it from village to village. (She looks quite popular, if a little silly in her crown!)
A nice two-fer, literacy & animal welfare education!
