Taking to the Airthrey?

Went to Stirling Uni today to meet up with an informatics colleague, so he could run through how some complicated GIS stuff works, in a way which an eejit like me could understand.

Afterwards, as I let my brain cell cool down at the Uni’s Airthrey Loch, I better understood the swans gliding serenely outwardly, paddling furiously below the surface, then taking flight to get to a happy place!
