Lol, people posting pictures at night. Yes, snow can and will stick to roads in March, but to act like there’s no difference due to sun angle is just plain silly. Anything remotely dark is sitting there absorbing radiation during the daylight hours at amuch higher rate than in Dec/Jan. Because of that you have to have good rates and/or cold temps to get/keep roads snow covered. You get light snow and 30 degrees in Jan and you will get/keep snow cover on hard surfaces, easy, even during daylight hours. March, not likely. So anybody saying that sun angle doesn’t matter isn’t being truthful. We all know it matters. It’s not prohibitive, but it matters.
