Thinking Outside The Box

Looks like a crop circle found in England but it is really just black sand integrated with Wisconsin sandy soil.   How did this happen?    Well, lizard aquariums need to be cleaned once and awhile.   The time was now.  My son just dumped the lizard waste right onto the driveway.  I like how the magic wand showed up in the image.   mmm, thinking Harry Potter......are you.....I am.
