Looking for Lynda

I love stuff like this- a padlock on the bridge at Falls of Feugh, the other side read "Lynda and Keith". Who could they be and why there?
I actually saw salmon jumping today too!
Misguidedly we then decided to climb Scolty- first time for the kids, damp swirling mist at the top, complete pea soup and no views at all. Not our finest parenting hour.
Betty has gone for a sleepover in a tent with Leo- very excited!
