Lost for ideas today and after last nights horrible photos, I had to get out and take a proper photo. Add to this, the fact that although Mrs B is one half of twins, the other half is about 3 hours drive away, so it was off for a walk up the canal.
So here it is, a photo of 'Twin' lock gates at Kings Langley (and I like it).
Great symmetry there, Bulldog, really like your choice of image for "twin". Love the colour of the water and the way your eye is led up the canal and into the distance.
