I finally came up with one recycling tub. I went out around sundown and started transferring the dirt to the "new" tub from the old Rubbermaid tub. The Rubbermaid tub disintegrated. Tomorrow I need to clean up all the pieces of plastic and the remainder of the old tub.

I just found one of those at the side of a busy road - it must have fallen out of a state truck. Unfortunately, the 5 gallon bucket that was in it had contained nasty chemicals of some sort.
