You will often come across vehicles that appear overloaded but then passengers will climb on the top of everything on the truck as well to hitch for a free ride. The Philippines does have some cheap ways to get round but some are high risk in my opinion with many low power lines. I remember reading last year about an explosion at a Sari-Sari store. What happened was a truck with LPG tanks had hit electric cables that shorted out on a tank causing the entire truck to explode. Would be good to see fruit heading up this way mind from the plantations further south and on neighbouring islands. Took us around 5 hours from Negros to Minglanilla and I am sure a truck would travel a lot faster than we could on the motorbike due to the 125cc limitations of the engine.
