One fine morning last year, (which in this story means bright sunshine, clear skies and river valley fog), I set out with a specific destination in mind. In the half hour it takes to arrive on location a slight breeze from the west entered the mix.
Rather disappointing. The tree at the extreme right is the buzzards roost featured in a previous post.
Same location, different day, with clouds and no fog.
For now, imagination will have to do the heavy lifting, this is more the idea.
