Riding on ice is no big deal if you have studded tires. If you've ever ridden on a fairly sandy, rutted dirt road, that is almost exactly what riding in snow is like (at least with the road conditions I typically get). To really enjoy winter riding, you just have to accept the fact that it's going to be different than summer riding. If you expect your speeds and distances to be the same as in summer, you're inviting disappointment.
