Here’s a bit of inspiration: http://canonfieldreviews.com/7d-1-weather-sealing/ (guy subjected Canon 7D and 5D Mk II bodies to a lot of water/snow abuse and they survived (Canon doesn’t guarantee rainproofing except for its professional 1D bodies, which are the same price and weight as a Hyundai sedan)).
So don’t let the cold weather, snow, slush, and freezing rain keep you from getting out. I will be cheering you on from my friend’s house here in Napa, California!
