Riakanau?
There were these buses called Riakanau - Leyland halisi - that used to ply the Embu route (I think). If you were anywhere on Thika road, you could board one, pay 1/3 the normal fare but you take 5 times the usual time to get to town. He he he. I wonder how people used to survive all the way to Embu or where they used to go!
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
