Oh wow dude, haha, yah, Oahu. You might want to hit up the HAC forums. It's like the biggest airsoft forums in Hawaii. We have 327 members and over 21,000 posts. ^_^
I know we got SEVERAL guys from the Big Island on the forums. Only one I can think of off the bat is Riki-o. Not only that but we also have plenty of guys who, like you, moved away from Hawaii and still stay in touch. Even guys who never been to Hawaii at all. I am one of the forums moderators. So yah, you should check it out, we'd love to have yah! ^_^ More the merrier!
