Slightly OT...
I am in Wales this week and was doing some walking along the Dee Valley, and stopped for Lunch near a rather nice stretch with rocks and fast water.
Get out Sarnies and start eating.
Out of the bushes comes an Otter, which then dives in the water, swims across and gets out on the rocks, thn repeats the process to gainthe other side.
Of course by the time I grab the camera it is in the bushes across the other side.
