I took my "usual passenger" on a 252 mile ride yesterday, me wearing my Tourmaster heated jacket-liner, she wearing a polar-fleece sweater under her jacket (even tho' I had offered my heated jacket-liner to her), along w/ winter gloves w/ glove liners for both of us. We started from Oracle (around 1,800' ASL), then thru Globe N to AZ 288, then up it about 15 miles to a good place (USUALLY...) for lunch at around 4,500' ASL. From the start the air was "crisp", but as we got higher it got CRISPER, and the snow level was quite noticeable as we rode N (and higher!).
Got to the turn-off to the lunch spot, a dirt/gravel road, but there'd been either rain or snow, and I could see and FEEL evidence that the road was 'soft', so rode carefully till a turn where it was obviously MORE mud than gravel, where I pulled off onto the higher side, turned the bike around leaving it running, and told her to remove her jacket.... I removed mine, then gave her the heated jacket-liner to put on, plugged it into the bike and turned it to MAX.
The smile on her face tells the 'whole story', her hands pulled back into the arms to enjoy the heat! After 5 minutes or so, I turned the bike off, we got back into our own gear, had a sandwhich, then I rode back UP (solo - standing on the 'pegs!) to the pavement, then came back to escort her up. Here's a pic of the mountain E of us showing the snow-level better.
At the end of a further hour and a half we arrived back at 'civilization', and into a heated home!
