Cove, I researched it. Hawaii didn't have any native turkeys, and Rios were imported. There were some feral turkeys on the islands from imported birds from Chile. But the main stock of Hawaiian turkeys came from 400 Rios imported from Texas in the early 60's.
My lack of interest in hunting them is partially because they aren't native to the islands. But also because a Hawaii trip is expensive, even if you aren't hunting turkeys. Plus, growing up in Florida, and having lived in the Florida Keys for a couple of years, I'm not really interested in the tropics any more. I'd rather hunt in terrain I've never hunted before, and if I was going to spend that kind of money, I'd go to Mexico for a Goulds.
Hope that explains it, if not, then, well, its just how I feel.
Looks like you are off to a good start on your US Slam, and you're a lot younger than me, so you'll probably get it.
