It generally does not go below 0 F around here. I ride on the snow and on the ice as much as possible every winter. Been doing it on bicycles since 1995, and motorcycles about 1970 or so. Studded tires make the ice easy. I'm usually within walking distance of a house, or a road. When one learns how to ride on slippery surfaces and what gear to bring it's not difficult. Not really a big deal. Frozen swamps and lakes are great to ride on, if you know it's safe, if you use the buddy system, and make sure your cell phone has a signal before riding on them.
Another bike in the snow, this one with studded tires. The last bike posted stays no studs.
