I think you got it all covered in one post, Ckimoo65. Good job!
To those who wonder what Hawaii might have to fill the niche left by the snakes: It's mosquito season all year round 
No really, we have a couple spiders with pesky bites, but no "poisonous spiders." If one hikes up into the forest reserve, watch out for feral pigs. You don't want to startle one or accidentally back it into a corner. Otherwise, they will run away rather than attack humans.
You have cowardly feral pigs

Wow! Too bad they don't eat mosquitos!
OT/ About the snake: My DH and I were at PetSmart last night buying a bigger home for our leopard gecko. The girl who was feeding the snakes and lizards had a small ball python wrapped around her neck!
She said that he was cold and that she was trying to warm him up. When I first saw her, I didn't know it was a real snake--it just looked like she had some sort of snake colored neck roll on the back of her neck.
But, sure enough, it was a real snake!
She is studying zoology at a local university here and we had a very interesting conversation. She knows a lot about snakes and lizards but her passion for when she gets her degree is to go "save the cheetahs!"
(Of course at PetSmart you expect people to have all sorts of animals on or about their person.)
