It was progressively less foggy as you left downtown. Drove from the CBD to Ferndale last night, and as we crept along Woodward and got higher and higher up in elevation, the fog would suddenly blanket the road. Woodward between 6mi and 9mi was heavily fogged, while downtown to Grand Blvd was totally clear. Actually it got suddenly more foggy as we went under the railroad bridge between Piquette and Baltimore. Then, there was a strange, spotty fog. Around Boston Blvd there was suddenly a huge blanket, then it cleared up considerably. From 6mi to 9mi it was extremely heavy fog. We couldn't see but 30 or 40 feet into the fog. One of the few times I've obeyed the 30mph speed limit on Woodward...

Would've been nice to have seen Detroit from the air that night.
