The highlight for me (other than being on the island itself, because at the time I had a huge masturbatory crush on a particular model's photos from the 1994 SI swimsuit calendar that had been taken on Mackinac) was running into former Senator Riegle and L. Brooks Patterson. My father spent about two minutes chatting them up and kissing their asses, and then when they walked on he turned to me and said: "Those guys are the biggest bunch of crooks in Michigan."

The beach on Tybee has this weird oil-like (meaning petroleum) substance just under the sand. I have no idea what it is. It's also fun to know you're swimming just a short distance from an undetonated nuclear device (http://en.wikipedia.org/wiki/Tybee_Bomb).
