Flotta

I nipped over to Flotta early this morning. Boat times mean just a brief time in the waiting room before the return trip, and there's an interesting display of information boards to read while you wait. 
I really like this map showing Scapa Flow so clearly and the depth of water.

The extra is a quiz - count the woodlice - for those who have read the information boards but still have time to spare before the ferry is due.
