Adam Smith

He of the Wealth of Nations. I remember him from my accountancy exams.
Lovely day out with intermittent sunshine and 4g signal. I managed 3 of 5 clues in a Lab Cache but the other 2 were out of signal range.
We’re at Aberfoyle where I put one smiley face on the map. We’ll be off to Loch Lomond then a whisky distillery. Sounds good to me.
