In formation

I went down to the river this afternoon to catch a blip and lost my spare camera battery. I searched for ages but couldn't find it anywhere so I headed back home to tell MrsW of my woes. She offers to come on out and  help me look. She is my good luck charm. There it is lying on the riverbank and to add a bonus to the tale the light is so much better on the river second time round! So these pics are from my second visit.
