Remember, the neighbors moved away. Love the liberal picking. As usual, voicing lots of verbal nonsense, but no intelligible information is coming out.
ANYwho, burn the stuff. I keep gallon containers in the Man Cave (Complete with Palin poster) to ease in starting the fire each night when I get home from work. Larger quantities go into the occasional bonfire or deadwood burn. Heck, even used antifreeze goes into the HOT fires. The stuff is flammable if you can boil the water off quick enough. A few times a summer some gets DRIBBLED on the dirt driveway on the prevailing wind side of my place to help with dust.
My boss claims he runs the stuff through a coffee strainer and lets it drip into his fuel oil drum. But then, he doesn't own a large tractor and doesn't generate the quantities we get.
I will, at some point, get around to making the oil drip that is mentioned here. Great idea for the overflow.
OR, you could send it to the imaginary polar bears in Antarctica so they will float better once they run out of icecubes.
