Traveled from Bawku, Ghana, to the capital of Accra by bus...That's basically all the way across the country, from near the Northern border with Burkina Faso the Southern coast. The whole trip took around 18 hours, including unexpected stops and delays and such. The concept of a consistent and accurate timetable for a journey did not seem to register in Ghana--it must be my own Western-centricism that I expected some modicum of a schedule to be a universally-demanded concept.
It was an experience, all in all, and was followed by another 15 hours or so bumming around the airport in Accra with almost no money.
