The hertzian waves were something of a mystery, magic in the air, intangible.
How, then, to harness the ether, to command it to bend to our will, to assist
us in speaking to the stars?

One man attempted to answer this question, and in doing so, changed the
world.

First, he reached one end of his house from the other. Then, he spoke to the
garden.

Later, his voice grew stronger, reaching farther than ever before, beyond the
range of vision and imagination, across the seas and through the clouds.
Around the world, people applauded, awed by that which was now possible.

Later, this man built towers, adorned with bronze. The towers reached into the
sky, as if to grasp the heavens and pull them closer to home. The waves
streamed outwards, a power never before seen.

In fact, another man even used this power to make his points. The spark of this
act is the location you seek. And, although the spark has faded, you'll find a
memento at this place to keep forever.

Under the northeast corner of the wooden structure, look underneath a small
pile of rocks....
