those suckers are a lot of fun to hunt. I lived in Hawaii, and they are really a pest out there on multiple levels. They uproot a lot of native plants, cause erosion, which, to a certain degree, runs off and is a contributor to the degradation of coral reefs. I've hunted them on the big island, on the slopes of mauna kea, where it's very expansive and you can see for miles. They can be so far away that they look like a little black dot in the distance, but if you get up-wind from them, they can smell you and will take off. It's pretty wild.
The best way to hunt them in a place like the park is definitely with dogs and I'd be more than happy to help. Get some good sausage out of it for sure
