What would the conclusion be if a parking lot archeologist came upon this layer in the sediment, many years from now? Much depends on the continuity of history. In the future where the slab pictured below is unearthed, would handicapped space indicators in parking lots still be blue?; would there still be handicapped spaces?; would there still be parking lots? What would be the alternate theories to explain this find?
Perhaps a researcher would consider this chunk of macadam a remnant of the almost forgotten 21st century art; perhaps a parallel discovery to the representational cave drawings of antiquity.
