Look up as you are reading my message, there it is yellow bar with"start a new topic" thats where it happens, and "head to head" is right over in the left hand corner. That is, if you are in the forum section of TMA.
And no I have'nt seen the Slings, South West wales is my favourite spot, though one day might do North, and Anglesey, but I'm not a collector of stone sites, just like to potter and think around the places I like best - Carn Meini is top of the list at the moment...
