Candice,
You're trying to get Hawaii right? I would think you'd be able to tell them you're willing to do the drive and not be compensated if that's the case. Not sure though.
Technically, for example, I think we could move somewhere in Texas that would be a bit of a drive from Lackland, as long as we accepted that we'd be responsible for that drive. Or, say we lived in Reno and the closest accredited center is Vegas... Well, if we accepted the PCS under the condition we knew we'd have to drive a few hours to Vegas for care, I think they'd still allow us to be in Reno. Am I right? Does anyone know for sure?
I think its more of a positive thing cause they can't put CFers out in the middle of nowhere with no services. If, for example, you DIDN'T want to go to Hawaii and they wanted to station you there, you could use the fact that you would have to drive more than XYZ miles to get care. They would not be able to station you there then if that were the case. So, personally, I've only thought of the EFMP stuff as a good thing cause it gives us a bit more control that we go somewhere we have access to care.
