I have never seen anything like this, so I call it FOG RAINBOW. We arrived fishing at 8,30 AM this morning, and this is what we saw. Ice, that was totally gone a week ago, was back. Lake froze over, again. It was so foggy, that everything looks like in dark. Temperature dropped from plus 9 C to plus 2 C, and stayed till noon, when we decide to go home, as it was too cold, despite of sunshine and very light wind.Does anyone knows, what would cause that phenomenal bow.
