The Giant's Quoit at Porthleven

Thanks to Rob Ixer for forwarding this one -- photo kindly taken by Nick Moore.  It shows how enormous the Gant's Quoit (at Porthleven in Cornwall) really us.  As fine a chunk of bluestone as we are likely to see anywhere.  (By "bluestone" I mean a chunk of rock in SW England which is obviously an erratic, having got to where it is by some process that we still do not fully understand........)
