Sorry to hear about your close call.
My father in law sold the timber on the farm several years ago, the timber dudes created several large slash piles. The picture has been posted here before.
One summer day a couple years ago, I burned a 'pit' out. This was an old rock quarry so it was mainly rock, about 5' deep. My goal was to burn the fluff in there to better expose the rocks so I could gain access to them. Within 30 seconds from ignition, I was trying to put fire out, within 90 seconds from ignition, I was running off to call the volunteer FD (love them guys)
They came out and put the fire out. (all this was BEFORE the attached picture)
WHILE they were out here, they saw the other large piles of slash that we had, so they took their bulldozer and dug a fireline around this monster pile. You can see my industrial backhoe behind the pile as a perspective.
Point I'm trying to make is, this fire was started with a fire permit in hand, AFTER the firefighters came out and essentially prepped the fire for me by knocking some stuff down and digging the fire break (from the first fire).
I lit it off, fire burned all day and most of the night (side question: how do you burn only "during the day" if it keeps burning?

)
Later in the day, my father in law & I looked over to another side of the hill and saw smoke.
As the wind had been blowing that direction ALL day, we just thought it was the accumulation of smoke... at this point though, the winds had changed and that area STILL had smoke...

I got a nervous feeling & walked up the hill to have a look see...
Seems several more acres lit off on the BACK side of the hill, where some embers from my 'legal' fire had gone UP in the heat column, over the hill and landed where there was more fuel on the back side.
I quickly called the fire department again, guy answered.. I said "are you one of the guys that was out on Coytee road last weekend????"
"yes"
"Well, I need you again...................."
While they were there, I went home and loaded up two large coolers of every kind of drink I had.... they woofed them down

I'd tried putting that first fire out, so I had a clue as to how they felt with these large ones.
Every year, we get a $75 bill from the local volunteer fire department to be a member. If we have need of their services, it's essentiall free. If we do NOT join and have need of their services, it's like $2,000 / hour for the first 2 hours and even more than that for more hours as I recall..
I usually send them $100 with my bill as a small (very?) token of my appreciation on what they've done for me.
Truth be told, what I'd LOVE to do is order some tasty bbq ribs from some favorite places (
Montgomery Inn - Home of the World's Greatest Ribs) and let them have a banquet "on me"
