Reminds me of when we used to grow cabbage and had problems.
Nothing like 5 gallons of gas and 50' of garden hose on a HOT day! We would drag the hose out of the hole just as we finished dumping all the gas down the hose and then touch it off after it had time to vaporize. WOW! Don't know how many we actually killed, but the explosions were fun.
I still remember the sight of everyone running when a skunk came out in flames on one of the holes.
