I went into there a few times in the CL30. It was at least 4000 feet long. I think there is a displaced threshold issue, and I've just read that there had been construction, making it 4,650 ft. That seems about what it was.
Also there is a terrain issue from one direction (can't remember, but it's the direction I've always landed in). That is easily avoided by angling your final a bit. It's kinda fun. (And great people on the island if you get to overnight.)
I have a photo of the field if you PM me your e-mail address, I'll send it to you.
