When I worked in Uganda I apparently had a name amongst the locals in the furthest project areas.
It translated as something like "White Rider".
This was because I always went out to the project sites on an old single gear bicycle rather than the Land Cruiser.
They grumbled to the local man I worked with that they never knew I was coming or from which direction as there wasn't the noise of an engine, and what was a muzungu doing riding a bicycle anyway, we were supposed to be too lazy !
(These 'suprise' visits lead to a few people getting in to rather a lot of trouble for work claimed to have been done but not, ..... they had some different names for me I'm sure !)
