I tried to find Kwachon Hari Korea in Google Earth but it was stumped. Would you have another town name?
Kwachon Hari, has changed the spelling. I was told by Korean representatives from the Korea CVB that things that started with "K" are now starting with "G". So it is Gwacheon-si.
I think the Admin for D/7//2 is located at 37˚27'44.49"N 126˚59'59.84". It looks like the fence shape. Plus at the bottom of the mountain. There was a ROK compound just to the north of us.
The Tac site looks like it is still active. Located at 37˚28'14.68" 127˚00'31.84"
