Four fifty something but young at heart travelaholics from England want to spend 3 weeks next summer having a road trip. We previously drove from Pheonix to San Fran in 3 weeks via various canyons, Death Valley and Yosemite and absolutely loved it. We have also driven Highway One - also brilliant. We don't want to spend the whole time driving and were wondering if Seattle to Chicago was reasonable or would we be better doing a loop from Seattle and ending up back in Seattle. We love national parks and wild scenery and music with the occasional city but are less keen on too long in cities.
We had also considered Seattle to New Orleans but thought it might not be a good time of year.
If anyone can help that would be greatly appreciated.
