The number one thing old farmers would do to disintegrate things in a burn barrel that is left over after several times of burning. Ie things that didn’t burn very well, they would very commonly pour old used motor oil on top and burn it. to burn it down to ash and make more room. Ok I’m moving on sorry for off topic. Anyways I don’t see any reason to doubt that pf burned kB in that trough and I believe LE is convinced he did as well. Moo
