Jamesey, you have a better memory than me and im not that much older
Can tell you the provinces ive been in over the last few weeks. Didn't spend longer than 24hrs in any of them except Davao Del Sur and my home province of Laguna. Have been in most provinces in Luzon and only a few in Mindanao.
Laguna
Quezon
Camarines norte
Camarines Sur
Albay
Sorosogon
Northern Samar
Batangas
Cavite
Rizal
Bulacan
Pampanga
Nueva Ecija
Nueva Vicaya
Benguet
Oriental mindoro
Would have to say my favourite is Laguna as we live here. Used to enjoy Mindoro but is now overrun with tourists Have a soft spot for Bicol but the wife says we cant buy land near the beach until we are retired
