Good news/Bad news:

Unlike during summertime, there won’t be a lot of traffic! Fewer long lines of angry cars stuck behind creeping, 8’ wide/40’ long RVs. Of course the downside is fewer passing motorists to lend a hand if you need one.

Unlike summertime, you won’t get sunburned after a long day of peddling. The downside is fewer hours to peddle and the likelihood that you’ll be cold and wet. HIGH likelihood.

Back to the “might need a hand” thing: you might want a SatPhone - cell reception is...dicey. At best.

Now that I’ve rained on your ride, HAVE FUN! It is a beautiful ride. (I like to do it on a motorcycle).
