I have read that the 2006 back fire was started on a day upon which BLM started a number of fires, too. The winds picked it up and burned 1, count it, ONE, acre of ‘federal’ land. The fire saved the Hammond house AND WINTER FEED.
In the movies, the Hammonds would have been heroes for saving their crops and livelihood.
I've read the same claims, but also read that burning was banned that day because BLM had fire fighters in the area who could have easily gotten caught up in an out of control backfire.
Selective facts don't tell a complete story. Again, best to hear all sides. In our system. that's what jurys are for.
