A female cyclist in the US posted (in a Facebook group) a picture of her late mum bike touring 'somewhere' in Scotland from 1938.
We had 2 images to go off...
the map of the route, remember this is 1938

And her mum with her bike somewhere on the monster route

So as I'm like most of you who love looking at maps and Google streetview I thought I'd take up the challenge.
I observed the shadow, which meant the image was facing east. I noticed the loch to the left of the pic behind the house. The shape of the hill in the background. The road, the bend near the bottom of the hill.
Surely it couldn't be found....
and then...
Boom! on Skye!

To say I was made up was an understatement, let alone how the daughter of the lady in the picture feels.
Also messaged a mate who is a copper on Skye later on and he told me its just been demolished to make way for a new build!
However just 2 miles north is an original road sign from that era!

So being a bit of a geek with maps/locations/imagery works well

Cheers!
