From then on my/our average speed would increase a bit...
Around 9 pm another bus comes along through the center of Isnos. This bus is full as well, but the driver agrees to seat us in the pass way for an illegal off-the-record one-time group-reduction/inconvenience allowance.
1 hour later I start to realize that the abominable state that the road is in is not gonna get any better soon. My body already aches everywhere from bumping up and down and is cramped from the tiny space it is crammed in. At a certain point the road is so bad that people fly out of their seats. Many of the passengers start yelling and whistling for a moment as a complaint and one woman in the back is nearly in tears as she yells at the driver that she has a baby in her lap. From then on the driver takes these points a little bit easier and the trips recedes to it's normal bumpy character. 10 mins later the bus stops and 2 mins later the engine switches off. We're happy to be able to get out of the bus to stretch our painful bones and some 5 m away from the bus we smoke a joint while joking about the driver being a pirate (he has no adjudant like all the others) and about how this was supposed to happen due to the bus' call sign: UJF666.
The driver and some other guy tinkle a bit with the engine and manage to start the engine over new, but it makes a loud rattling sound (supposedly from the water-cooling fan). The engine is switched off and the problem fixed. When walking back to the bus, I see through the front grill that a fan (supposedly from the water-cooling fan) is not running. An hour later this happens again, which makes me happy, as I was in a far less comfortable position as before and thus desperately watching the public speedometer lingering between 6km/h and 22km/h at the most.
Again the problem is fixed in 15-20 mins. We stop a little later again to eat a piece of bread with some unbranded, white cheese and a cup of hot Panela, company service.
Two other stops (problems with air-pressure) and three hours later we climb out of the bus at a place that appears to be in the middle of nowhere. It's 3 o'clock at night so everything appears that way. A local that helped the bus driver to some more air points us in the right direction and tells us it's an hour walk to the hot springs and we're on our way.
