My girl is fluent Ilocano, Tagalog, and English. I am sure she would be able to help, but sadly she does not now have easy access to the internet. If all else fails, let me know and I will try to get a copy to her, but it would have to be by post.
I was quite amused when we were at Batad recently, and our guide was talking to the lady at the information center about us using Ilocano. He did not realise that she could understand everything that was said, and you should have seen the look on their faces when she chimed in with them. Thankfully he was not at all critical but quite the opposite in fact, but nonetheless was still very embarrassed !

By the way, we followed some of your recommendations in your old post titled " Cordillera Triangle" and found them very accurate and helpful...........Thanks very much.
