16- These curb stones run along the Boothem area of Central York, all i tested were attracted to the rare earth magnet shown, i did not have a none rare earth magnet with me, but would gamble one would easily stick,as ime sure these stones originated from one of the quarry's in The south west area of Cleveland.
