So I'm driving the wife and baby up to Wisconsin for Christmas this year, and since there's a good chance we'll be driving through heavy snow sometime during the week, I figure getting snow chains is a good idea. Problem is I grew up in North Carolina, where we cancel school for a week for the mere forecast of flurries, so I have no experience with what to look for, what to spend, heck, even how to install them. Anybody got suggestions, recommendations, horror stories, etc. to help me out?

Thanks in advance!
