Golf Ball

It probably does have a name, but I don't know what it is and the locals just call it the Golf Ball.  There was CCTV everywhere and I did just wonder whether a drone would appear from the sky.  But no.  

/edit - a quick search would have been helpful - it's an air traffic control centre.

Kylie (and to be fair, we) needed a good leg stretch so we headed up Lowther Hill on a bit of the Southern Upland Way track and then back down again via the pub in Wanlockhead.  Then back to the fire and a G&T before dinner.
