Well, I have to tell this story. I pulled about a dozen 30 to 40 foot spruce trees out with the excavator and piled them up. Called the fire Marshall to burn it and he said you have to wait until the snow flies. I was good with that since I live in a log home about 250 feet away. So, summer turns to fall, fall turns to winter and it finally snows. Me and my buddy go out to light the pile, thinking this will be a couple hours and we will be drinking beer. 18 hours later, we went to bed after (and I kid you not): 40 gallons of diesel, 20 gallons of gas, bales of hay, 6 fireplace logs and a few gallons of citronella oil. **** stuff was pretty much fire proof. Every time we would get a fire going (and we started 6 at a time), all it would do is burn a hole up to the sky and go out. We ended up starting a fire and hand feeding it for 18 hours. Now, I've been burning stuff for 50 years, but I would have been much better off burying this stuff. The next day I had a pile of smoking stumps that I had to get rid of and a massive black hole in the meadow I had to repair. Go figure, we just couldn't get this stuff to burn!
