Basically as of 5 pm today Most of northern California (inland from the coast) from Bakersfield to Oregon was heavy smoke

I mentioned before I  think that I couldn't see the Sierras once traveling up interstate 5 from Santa Nella where I first got on Interstate 5 today all the way to Mt. Shasta. IN fact, I couldn't even see Mt. Shasta at all (which is unusual unless there is a rain or snow storm) until I was right in front of the Lake Street Exit which is the main exit from Interstate 5 into Mt. Shasta which is very unusual. And even then I wasn't sure what I was looking at and likely would have had to stop and get out of the truck to make sure I actually was looking at Mt. Shasta through the heavy smoke.
