My best was Idaho in the late 1970's. My buddy (Tim) and I would hunt jack rabbits during the peak of the infestation.
The next day Tim called and said he couldn't find his wallet. It had a photo of his late mother, Navy ID card, etc, and he was pretty torn up.
We had 12 hour shifts at INEL. Before we could go out into the prairie sage fields and retrace our hunting path near Pingree, the area suffered a wild fire. The fire scorched everything.
None the less, we went out and retraced our steps. I stopped the Jeep and said, "This is the spot we stopped last week."
I opened the door, looked down and there was the wallet. It was sitting on ash, slightly singed.
Luckiest day of my life.

All Best,

Joe
