An inquiry to the local authorities told us you can have a recreational fire in your firepit pretty much any time so long as the fuel is below the rim.
So the Excavator dug a hole 15' deep and 15 wide. The dirt was heaped around the rim like a mini volcano and planted with tropical plants. You know, in case we put too big of a tree in there. Well actually 2 trees was usually about right.there was a fire station pretty much right next door, so they saw the 40' flames out the top of this thing and came right over.
Fireman;" WTF is wrong with you people, you can't do this."
Resident; They said if our fuel was below the rim we were OK."
Fireman;

, " I hadnt really thought of it that way. Thats pretty cool, feel free to call us if you have any trouble."
Resident; "Thanks, do you guys want a beer?"
Somebody got a little too gung ho lighting it one time, and had a bit of a fuel air explosion. Not only did we blow out 17 windows, but the glass delivery guy didn't heed the warning about going slowly up the bumpy driveway, and broke almost every one...
twice! But the mean neighbor lady took offense and sued us for disturbing the peace with 'loud and mysterious explosions'. Luckily she couldn't prove anything.
If there had been digital cameras then, we probably would have been screwed.
