Aloha @Alanaana! Nice catch. Skinning may be simplest. I have also seen folks pile vegetation on top and burn the hair off. That way, you can save the skin and crackle it. If you are on the Big Island and want to do that, I can save you a truckload or two of dry cane grass. Won't cook the pig, but will burn off the hair.
We just cut and pull. We use a sickle and/or machete. Roots pull out better when they are dry. I’m in HPP. Where are you?
