Sometime in my life I plan to live on Maui. I have been there visiting a friend who is a lifelong resident.
We rode our motorcycles all over the island (On the road to Hana, and up and down crater road countless times)
We toured their cattle ranch- Haleakala.
The back side of Haleakala has some good Ulua fishing, but as you said You never know what sea creature will take that hook.
