Then I noticed the vibration traveling farther.
Toward the eastern edge of my property.
Toward Bellweather Pines.
I followed it until I reached the fence line.
At 2:10, sprinkler heads across the subdivision rose.
Hundreds of them.
Almost simultaneously.
Water arced through landscape lights.
Median grass.
Front lawns.
Trees.
A drought-restricted neighborhood watering in the middle of the night.
I looked back toward my pump house.
The pump continued running.
That was the first moment I seriously considered the possibility that my well and their green lawns were connected.
