Download(Helicopter blades whirring)
Just one month after moving off the grid in Northern California,
I was alerted by this sound.
I went outside to investigate to find this helicopter circling.
That's when I realized
my neighbor's ranch had a wildfire running through it.
The pilot started waving at me, probably to evacuate,
but I stupidly grabbed my garden hose
and started watering down my house instead.
Shortly after that,
a huge air tanker flew directly over my head.
I watched the bomb bay doors open as the retardant went flying.
