Unfortunately, I simply didn't exercise enough after lunch, and I ate too much, with the result being a 209 blood sugar an hour later, and even more troubling, a 200 reading an hour after that. (Usually if I get a >200 spike like that, it will come back to normal an hour later.) One more hour later it was down to 141, which at least meant it was finally retreating to normal. Exercising while traveling is tricky.
Siskiyou Pass was no problem at all -- no rain or snow, wet pavement in spots. It was Black Butte Summit south of Weed that was troubling. The clear weather out of Oregon turned into rain and then snow around Weed Airport, and the wind gusts over Black Butte Summit (almost as high as Siskiyou). It was snowing heavily at Mt. Shasta City, where I stopped briefly. Snow continued until well south of Dunsmuir. Fortunately, it never got heavy enough for chain controls to come back on. (Chains had apparently been required earlier in the day.)
Now I must eat a small bit -- not a lot, in light of my blood sugar incident earlier today -- and get some sleep, because I have multiple conference calls tomorrow, and I can't work from home all day, as there is stuff I must collect from the office.
