Canada is the only place. It's only about 15 minutes from my home though, so it's really just like driving to another town for us. I've been to lots of places in Ontario - Fort Erie, Niagara Falls, Toronto - those types of places. It's a very beautiful country - they take great pride in keeping it looking spectacular (well, in most places anyway).
Name one quality about your SO that makes you sure he/she is the right one.
Drive thru the Badlands and Black Hills of South Dakota--see Mt Rushmore and Devils Tower and head over to Yellowstone (ok, so that's probably more than a week)
