A friend told me that he was on Skylink going between terminals...and it broke down at terminal E.

He had to go into terminal E and exit security. Due to all of the extra people the shuttle bus was overwhelmed, he took a cab over to D, and had to re-clear security (thankfully he had PreCheck). He made his flight, but it was a bit close for comfort.
After I heard that story, I've walked C-D, D-A, and nearly anything else I could. I normally participate in FitBit challenges, so the extra steps come in handy.
