Thieves Around the U.S. Stealing
Manhole CoversJuly 8, 2008 Earth First
A sign of true desperation: with the U.S. economy sagging, people have started resorting tostealing manhole covers to sell as scrap metal. The price of metal has skyrocketed lately, so
thieves around the country have started stealing the 200-lb covers by the hundreds. Funnything is, for all the effort it likely takes to haul off an iron manhole cover, you can only get$10-$15 each for them.
Its a sign of the times, says Sgt. Jay Baker of the Cherokee County Sheriffs Office inGeorgia, where 28 manhole covers disappeared in April and May. When the economy gets
bad, people start stealing iron. Long Beach has lost more than 80 covers this year. People who have damaged their cars
driving over manholes have filed claims with the city, Alsop says.
Our No. 1 concern is safety, he says. A small kid can fall into these holes, which can be 20feet deep.
Hey, I guess meth heads gotta get their fix somehow! Seriously though, whats next? Theyrestealing copper wire off construction sites, catalytic converters straight from parked cars allover the place, and now manhole covers. Should I be locking down my metal patio set?
