Before a rain, I put the recycled rubber (former tires) feed tubs all together and turn them upside down off the ground, to keep them out of the mud. We had a big rain storm, followed by a freezing fog the following morning. The fog had formed ice crystals on everything, so I had to go get my camera (of course!) and photograph some of them. This is a macro photo of the bottom of one of those rubber feed tubs. Look at the full size version. I had so much trouble deciding which photo to post, I put them both up, and could have added a dozen more. The ice crystals are fascinating!
This one is a horsehair caught on a splinter of wood on a fence post. Barely visible usually, the hoar frost gives it the appearance of yarn.
