When the snow melts, do everything recommended above, plus whatever you can think of to keep your feet warm. Neoprene toe covers, Gore-Tex socks, etc. Another thing, allow extra time since each time you stop to record something or paint something, it will take extra time removing gloves, opening zippers, awkwardly writing or painting while holding gloves, then re-dressing and re-zippering.
How long before the roads in Michigan are clear enough to measure, after a snow storm? We, one time, had the race director shovel a path through the snow piles at the corners to let us measure a course he changed a few days before the race. We had 2-feet of snow 9-days ago. Since then we've had 4 or 5 40-degree days. The piles at the corners will be there for at least 2 more weeks, if there's no more snow.
