Have you been to Caylabne Bay Resort in Ternate, Cavite?

On the way there after Puerto Azul, there's a magnetic field area. Since this is mountainous, the roads are rolling. And, if you stopped at the lowest point of the road, put your gear to neutral, and released the brake, you car would roll towards the highest point, defying the law of gravity.

There's also a similar magnetic field area in Mount Makiling going to the Jamboree site and UPLB.
