Treasure hunt

We have a group of friends up next week and one of the things we were thinking of doing is some form of treasure hunt so off we set trying to sort something out.
It was really just an excuse to visit our favourite places on North Uist in what was some stunning conditions. 
This view from the car-park at Grenitote is one of them and the light provided enough drama today. Glowering grey over the Harris hills but bright sun here. Who needs to go to the Caribbean when we get colours like this?
That said not awfully tempted to get into the sea.....
