I was passing through the national forests of Oregon and Northern California the other day, and what strikes me strange is that the smog was extremely heavy in NoCal. I thoroughly enjoyed the drive in Idaho, albeit with some excitements over narrow roads without guardrail over a steep cliff. In California, though, it's a different story.
First of all, I noticed that the sun was strange looking. More reddish orange than bright yellow. That indicates the presence of oil. And indeed it wasn't smoke, but smog. The air is terrible, and this was on national forest! I didn't enjoy this particular trip.
The next day was spent in Sacramento. There must have been a heat wave or something. The temperature was in the hundred. Also, the air was filled with extremely heavy smoke. The thick smoke continues until I get to Wyoming. I was rather disappointed to see smoke in Nevada. At least in California there were trees to absorb the carbondioxide. I noticed the trees in California seemed more tired than the ones in Idaho, though.
Salt Lake has Bonneville salt flats, where they do all those speeding. I notice quite a few messages with stones formed on the side of the road. I usually enjoyed this part of the trip. The smoke just ruined it for me this time. I wonder how Yellow Stone fares?
