Looks like a Pangasinan 3rd Leg
The Pangasinan Provincial Capitol would be a beautiful Pit Stop location.
Lots of tweets spotting Derek at Our Lady of Manaoag (with Derek himself
tweeting a pic of a rosary which he, I would assume, bought at the church
) and at the Lyceum-Northwestern University in Dagupan.
So right now it would appear:
Leg 1: Manila
Leg 2: Imus, Cavite > Bauan, Batangas
Leg 3: Manaoag > Dagupan > Lingayen, Pangasinan
