Or roughly 30 hours of highway driving.
See also google maps:
I like their hybrid maps, which combine satellite imagery with highway maps.
Now that is based on driving through the states, but I would stay in Canada. Although USA is a great place, I think it would be a bit more pretty to drive through Canada. Mainly around the Great Lakes.
If you need help with places to stay just feel free to ask. I am willing to help!
P.S: Check out www.mapquest.com, it is a really great site.
Hope this helps!
Oh, I forgot.
I second Jerm's suggestion of www.google.ca and their maps. They are really great!
If you are thinking that it is cheaper or quick to drive, don't do it. However if you have a couple of days and want to see some of the country and the northern US, then it is a nice trip.
