ziplocks growing on trees?

Things you see in Africa are just different to elsewhere - in Ethiopia this might be donkeys crossing over pedestrian bridges, blue and white mini-bus taxis crammed full of people or such like. Well here is a new sight - ziplock bags hanging on trees.

We re-use everything wherever possible here so ziplock bags hanging drying is a fairly common sight, ours hang in our kitchen window, others have been spotted on clothes lines and it would seem some are drying on a tree :-)
