ive lived up north my whole life. 4wd will help you in the snow, though we have had snow this year and a lot of the time you do not need to engage the 4wd and cause just run on 2wd. for ice, 4wd will not help you once you hit the patch. it might help if you are heading up a hill, but do not expect to be riding the freeway going 60 and just because you have 4wd expect it to keep you from sliding. there are plenty of idiots who thinnk because they have 4wd they can tackle everything and drive the same as if it was 85 and sunny.
