Good work, Ovalorange! I only had the middle one. I don't think any of yours had been posted. Tats? Temporary ones I hope.
From what I'm able to figure out, Magic Island is not an island, but the man made peninsula between Waikiki and Ala Moana beach in Honolulu.
Here's what I've found:

Also, from Facebook:
<Our Witness> I almost ran over a woman running in front of me on my way to the dump. Turns out she was in a hurry. She was part of an amazing race team. Kewl beans!

<Our Witness> they came up behind us and wanted us to pull over to ask for directions. We might end up on the show.

The Facebook witness is from Laie, Hawaii out on the north shore of Oahu (or at least on the way there). The only dump I could find was way over on the west side of Oahu, so I can't tell for sure where the witness was when the encounter happened. However, a few days ago I did find some indications that TAR France may have gone to Turtle Bay on the North Shore of Oahu, so this sighting may fit with that.
