Dawa you will be fine,i born and raised there and i am forth generation born,my parents still live there and it is a beautiful place to live,the only reason why i left is i used to run all the tanker barges and tug boats out there for at the time BHP and then Tesoro bought the refinery and i was laid off 2 years later so thats why i left.I dont care what any body says just fit in with the locals and you will be all good.The worst part for you is higher gas prices but hawaii has one of the best bus systems in the United states so maybe use it and the recon sticker like tiki said but thats not a problem.
Go have fun and be a Hawaiian,no forget Zippy's and i want you to go to Libbys manapua and try the pork hash,and you let me know if it is not one of the best things you put in your mouth to eat.[other then a big cock,nah just kidding].
ALOHA
