Going to the beach with Signal #2 raised makes for lot's of fun!
Montemar has a Pawikan conservatory (they release babies during November so I want to go back for that)
We went to the Dambana nang Kagitingan on top of Mt. Samat, and Ernestown Isdaan (awesome food). We also went to the Bagac Cashew Nut Processing place to get pasalubong.
We used SCTEX going back to Manila - it has the best view ever (although they cleaved mountains / hills in half to make the road)
