Polybian Romans

Or they dipped the horses' feet in 'Round up' !

Years ago, the next door neighbour used that particular weedkiller on his brick laid patio......And then walked over his pristine lawn to his garden shed.
A few weeks later you could see where he'd walked by the 'dead grass footprints'.

The neighbour's wife was NOT amused.
