The 'frost on the bike' photo reminded me of a December trip I took across I-10 a few years ago. Stayed in Sonora, TX and woke up to a real cold day and snow along the highway. Heated grips and an electric vest made riding quite comfortable.
FWIW, I always travel with a lightweight, black cover for my bike that packs up in a small stuff sack. In addition to providing a bit of protection from the elements it also makes the bike less conspicuous when parked overnight.
