I use Royal Oak strictly. I've found lots of rocks, something that looked like cooled molten metal or something, and fiberglass insulation. I even found a hunk of insulation about the size of a nerf football once. If you let R.O. know you are finding weird stuff, they'll hook you up.
Is that still true? I've been only using RO and out of the past two 10 pound bags I have pulled out about 2 pounds of concrete. Their website doesn't work and wasn't updated past 2001. Online I found mention of the bad economy having them shut down the GA plant.
