Wes,
This isn't quite along the same lines, but when I was a kid, and yes at one time I was young, I worked on a dairy farm during the Summer. They would pile the cow manure in big piles outside the barns and then load it onto manure spreaders and spread it over the pastures. One particularly hot day, one of the big manure piles blew up and scattered all over everything. They said it was from the methane gas building up in it and the heat. They had left it stacked to long. This I know because I had to spend a couple of hours helping clean up the mess.
