If you were wondering how to reach the Elf Kingdom...

I think I found the place.

Yup. A real sign at Vanderbilt Children's Hospital.

In the basement.

Next to a really tall door with a handle about eight inches from the ground.

And apparently if you open this door, in has a ladder that will take you down into the depths of the hospital... and into the Elf Kingdom.

Just thought you might want to know.
