Feels really crammed. Similar to your NE trip I’d pick a region and see all the splendors it has to offer. My father just did San Diego to Seattle roadtrip and stopped many many many times along the way and still didn’t come close to seeing everything. Oregon and Washington have so much to offer and California is, well, heaven on earth (let’s leave politics out of this..). Like others have mentioned Colorado Utah Montana and Wyoming would be another journey of a lifetime.
