Castell Coch with boys

Had the lads overnight so we took them to Castell Coch near Cardiff.
Spent ages playing in the fast flowing, shallow stream making dams and getting soaked. Followed by a bite to eat and a coffee in the Castell, a good but soggy few hours. Spent most of tonight trying to fathom out how to format an external drive to be read by both MAC and PC. Finally managed it so I now have a simple way of transferring files between all devices without the dreaded cloud!
