Doesn't look like I'll be headed back to HI after all (DC instead). As far as I know there's no one there teaching Uechi. I had one student studying with me regularly when I was there a couple of years ago - I believe he moved away but if you're interested, PM me and I'll see if I can find his contact info.
Good luck, and if all else fails, just remember you're in HI - how bad could it be?!
