English: Sierra Madre (Philippines)[1]The Sierra Madre is a mountain range in the Philippines. It is located along the north-eastern coast of Luzon Island, running north/south. Quezon National Forest Park is situated in the range. Gabaldon, Nueva Ecija[2] (formerly Sabani and Bitulok) is a fourth class municipality in the province of Nueva Ecija, Philippines; it has a population of 32,246 people in 2010. Ilog Carugang (Carugang River) serves as the gateway to Sitio Carugang, a far-off place in Gabaldon, Nueva Ecija. The river has been a silent witness to the harvesting of what the people of Carugang had sown, for merchants have to cross the river so they can buy the crops the farmers planted and reaped.[3]
