Lots of interesting things seem to be very well-preserved in Britain's moors. Can't wait for them to sweep the whole lot of them with ground penetrating radar.
Have been having a blast with my 8 yr old granddaughter and a metal detector (Not one for precious metals). We found 5 horseshoes in about 10 minutes. Finding horseshoes with a grandaughter is better than finding gold...but we have 100 acres...so who knows...maybe a chest will turn up!!
