Trip na Trip goes back to Palawan.
This is the teaser of Trip na Trip's upcoming episode on 9/4/09. Had difficulty in guessing which province they will be visiting because they didn't name it in this teaser. Their clue "#1 Eco Tourism Destination in the Philippines" is still general so I just looked at the clips. The clip wherein Franzen was with a logo of DOJ - Bureau of Corrections gave me the idea about this place in Palawan. And I was right that they'll visit Palawan again and part of their epi is on the infamous Iwahig Penal Colony.
