I grew up in the small town just south of this stone, Dalgety Bay.
It's great to hear it's still standing as last time I visited about 10 years ago the farmer told me that it was getting knocked down and houses were being built on top of it.
You can get to this stone quite easily. Get the train to Dalgety Bay from Edinburgh, come out the station and head left along the main road. You will have to walk on the opposite side of the road as last time I was there there was no path. The entrance to the farm is the first turning on the left if I remember correctly, and the stone should be clearly visible as soon as you turn in - it stands on a hill on a field to the left.
You can also get a 55 bus from Edinburgh to St Andrews and get off at the first stop in Dalgety Bay and walk up to the station - only takes a few minutes.
I visited this stone today on the way back from a trip round West Lothian. This is a large block of sandstone, seven feet tall and approximately 3 feet wide, and runnelled in a fashion very reminiscent of the Tuilyies main stone only a few miles away. The field it stands in is usually home to some horses, so ask at the stables here before going into the field. The lady there told me they will soon be erecting a fence around it to stop the horses rubbing on it, at the behest of Historic Scotland.
