Pahiyas 2010 in Lucban, Quezon: the feast of San Isidro Labrador, patron saint of harvest and it's celebrated annually in May 15. Go early, preferably a day, so you are assured of a place to stay as the whole town will be closed to traffic. If you have relatives, the better. I am glad we have relatives there (they're posing infront of the building).
I've seen Pahiyas twice and it's beautiful! It's been featured on public television here in the U.S.
