I have fire extinguisher story. My Dad and I used to have cattle in the hills and about this time of year we would spray them for flies and ticks and stuff. Just get them in the corral and go in there with a spray nozzle and a hose. We had a tractor with a 100 gal 3 pt. sprayer and my Dad was pulling it up with his about 1982 chevy pickup. There was a really steep hill just before our corrals and this got his automatic transmission hot and it spewed out oil from the dipstick tube onto the exhaust manifold and caught on fire. We just looked over at the pickup and the grass was burning under it, I hopped in and tried to move it, but it had already burnt some of the ignition system and it started but didn't have enough power to move itself. I had just bought a small extinguisher at the hardware store about a week earlier. So we are all running around (like a chinese fire drill) and I went and got my new extinguisher out of my pickup we popped the hood and I gave it a squirt and the fire went down and then came up again and I did this two more times and the fire stayed out. I was going to put the rest of what was in the extinguisher on the smoldering motor just for good measure and it gave one little weak gasp. Those little extinguishers have 3 short squirts and that is it. I went the next day and bought a bigger one and haven't used one since.
