The Sign Of The Phantom

"Phantom" road signs left on the road with no obvious work about piss drivers off. Fair enough too. It does happen as the industry acknowledges;

While in the majority of cases, speed restriction signs are realistic warnings, the industry has put its hand up, and conceded that in a few instances, speed restrictions signs are inadvertently left out when the hazard is past.
“The old ‘cry wolf’ story is as true as it ever was. So because we don’t want New Zealand drivers to think speed restrictions around unmanned road sites are irrelevant or don’t apply to them, we’ve set up a website where they can log in and say where they believe the signs are out of date or unnecessary,” Mr Brown says.
The website is www.slowdown.co.nz
   In our case we have the opposite problem. The boss is always wringing his hands about signs that are still up. Signs are worth big money, most are made of high grade aluminium. We lost a lot one Christmas, I think I know where.
A woman stole 183 road signs worth almost $20,000, hoping to sell them for scrap metal so she could buy Christmas presents, Tauranga District Court has heard.
Jocelyn Kiri Ngawaaka Ngatai, a 34-year-old sickness beneficiary, was jailed for six months when she appeared before Judge Michael Hobbs this week.
I Hope she had a better Christmas than we did. Out for 36 hours straight in pissing down rain, and falling rocks, dealing with 11 slips that had come down through the night. A day after we finally got home all our warning signs were pinched. A car and a motorbike ploughed into later slips as a result.
