wow this is inspiring! i am so taking photos of this area... actually tagal ko nang gustong mag shot dito sir, kaso hirap nga lang huminto. highway kse! hahahaa 
pinag handaan ko talaga to, I always pass the area and one friday morning, naghanap ako ng spot talaga na maganda kaya lang panget yung sky. Immediately, a week after that I've read from a weather website that we are expecting cloudy sky, so woke up early and drove to the same spot and just waited for a good time to take the picture. Although the clouds does not look that saturated, I always have photoshop to help me.
