^good to "see" you again, callippo. Are you back in PI or still trotting around?
Re: du30 & Boracay, yeah, Boracay needs to be cleaned up. Last year, it was flooded before Xmas due to rains from typhoon Urduja (or was it Vinta) - saw pics in the news. It's a small island and it's been overdeveloped. There was a study by De La Salle Uni some years ago that they found fecal coliforms in Bora waters. Seems the problem hasn't been addressed properly. When I visited there in 2015, there were still lots of construction for new hotels & guesthouses.
Edit: Bora still draws in tourists. Last Xmas season, I rode the 2go ferry (Batangas-Caticlan) to go to the province. Lots of ppl on the ferry were off to Boracay for some holidays.
