The unpredictability of traveling in Africa

So, I'm not starting my hike today, like I was supposed to.
When I was waiting for my bus in Mombasa, Keffa (my travel agent) called me and said that my departure was being delayed one day. That was less than twelve hours before I was supposed to leave for Tanzania... So I came back to Nakuru and am still waiting for a green light.
Appearantly the guide who was supposed to take me, took some other guys up there first and isn´t down yet... hmmm... but Keffa is still assuring me that I WILL go, that's 100%, well, as much a hundred percent as anything can ever be here in Kenya.

If you don't hear from me within three days, I must be on the mountain. If it doesn't work out, I'll tell you about my plan B as soon as there is one.

It actually was convenient that I didn't have my bus to Tanzania yesterday morning, because the overnight bus from Mombasa got delayed...
It arrived late from Malindi, but the boarding went quickly and soon we were moving. But not for very long. After just 1000 meters or so, it stopped and was left running, so we just waited. After having waited for about twenty minutes without any explanations, I went out to check what was going on. Some of my fellow passengers pointed to a leak from under the bus. The driver wasn't there and no staff available to tell us what would happen.
The tension mounting with the passengers, half of them soon decided to go to the police. I stayed in the bus, because I couldn't be bothered to carry all my luggage around.
But just five minutes later we were moving, - jerky movements indicated that the driver was not very used to drive a 50 passengers bus. My suspections were confirmed by a fellow passenger: the bus was being taken to the police with all of us in it. The driver had some difficulties, held up traffic when backing very slowly out of a wrong turn, and rounded off a few corners and crossed some roundabouts.
Appearantly, we weren't headed for the police, though, we came to a stop outside the bus office, where it had all started over an hour ago.
Word got around the bus that it wasn't anything wrong with the bus, but it was the driver that had driven from Malindi, he had quite simply run away soon after leaving the bus office. So we were provided with a new driver and soon the bus started moving again, (after having been pushed onto the street when it wouldn't start). This time we only got as far as a hundred meters before stopping and backing back to the office. Another unexplained wait of around twenty minutes and finally we could get going, two hours and twenty minutes after we had been supposed to leave.
