I parked at the Airlie village hall and walked back east along the A926 jumping the fence near the stone. The stone has been put back up, has had some field clearance/chokes removed and now has a nice fence surrounding it. Nice setting to restart with.
This stone is situated near Alyth. Taking the A926 east from Alyth, through Ruthven and the village of Airlie, it is immediately visible to the right, highlighted against the sky. There is a convenient farm gate nearby, which can be parked in short term. The stone is over 2 metres high, and has no normal distinguishing marks (If you disregard the ruddy great bench-mark on the northern face...), but is quite dramatic as it leans to the south, illustrated in the picture I have posted.
