Related to routing, I mentioned this before.  I am documenting
inter-town routing.

Starting from Luneta Park KM 0, I am using yournavigation to test
routing leading to the rough location of each town in the Philippines.
 When routing fails, I edit the data and revisit in a few days.

The spreadsheet is here:

Anyone is welcome to add more yournavigation links and comment if
routing provided is OK.
So far, I was able to test and fix several towns in Bulacan, Cavite,
Batangas, Laguna, Nueva Ecija, Rizal and Ilocos.
