Pavement artist

We saw the reason for all the colorful markings on the pavements and street today - work in progress.  The 'graffiti' obviously indicates where underground pipes are located as the man seems to be using some sort of metal detector and squirting that pink paint on the places he can detect it.  Arrows and numbers to be added later...

A smaller party (Grandad, Sam and I) didn't stray far today but still ended up on the main shopping street (see extra).
