Note
Thanks to arthurd's rec, I added some XC ski boot covers to my gear closet today. Given that there now isn't -30C weather in the forecast for this upcoming Timmins trip, I am trying to console myself by thinking they would be good boot covers for biking too.
Timmins temperatures are from +4C to -20C this weekend.....I put the red (warmer temp) wax on tonight, and will take the blue, in hopes that I can snag some time with an iron at the Porcupine Ski Runners centre once the temperature drops. These are waxless skis, but Goose introduced me to the wonders of waxing waxless skis, and I can't go back now!
