I’m near one of the detection devices.

They wanted to put windmills on a mountain nearby but vibration from the turbines would disrupt the sensors. There are two perpendicular arms about a mile long in the setup.

Unfortunately, they may not be able to detect a graviton, see video

Seems like there should also be a vertical tube for a true x-y-z setup. 3D gravitational waves! The mile-high leg would also be a big tourist draw!
