One week in mid-October, 4 people (3 of whom will take turns driving), starting in the Hudson valley, NY.

How far can we get? What can we see? The original plan was to make the Grand Canyon the goal, but I think we'd end up getting there, seeing it, and leaving the next day to drive back, so we're looking for new destination ideas.

We'd prefer to head west, rather than north or south, as we've been all over the east coast, but none of us have seen much of the midwest, southwest, or northwest of the country.
