Pea soup, or a pea souper is thick fog, especially a yellowish smog caused by the burning of soft coal. http://en.wikipedia.org/wiki/Pea_soup_fog
As a matter of fact, as the fog and clouds came rolling up the field, I though it was smoke. It moved with such speed. I struggled into shoes, and shuffled out into the rain to see what was burning. Luckily it was nothing. Just the clouds making it over the hill. In the picture above there is a deer in the middle left. See it?We have had a lot of rain in the past day, and it continues tonight. The stream is way up and quite muddy. Tomorrow it will be worse. I'm sure there will be flooding problems around. Hopefully not for long.
