Jeanie is most definitely not a "car girl". She has mistaken a Suburban for her Town and Country minivan because they were both silver. If she could arrive at her destination by means of teleportation, that would be her preference. I get that.
She's good for about 4 hrs in the Speedster (or any other car), before it's not fun for her. She's one of the toughest people I know, and will push through almost anything, but I try to respect her enough to work around what's enjoyable for her. She likes the car in small doses, and I'd like to keep it that way. US 40 though Nevada was one of the highlights of my life. Jeanie once declared Yosemite inside the north gate to be "a fancy gravel pit" (after 8 hrs in the right seat, a mistake I've tried hard not to make again). We've figured out a way to accommodate both of us.
There are exceptions to every rule, but most of the women I've met have a similar outlook on "empty horizon" traveling. Jeanie would do anything for me, but she derives no joy from sleeping on a bedroll in the desert, and eating almonds and beef jerky from a ziplock bag. David's wife is clearly the exception to the rule, and it makes his trips frankly epic.
For us, there's a significant difference between a vacation and a journey of discovery.
I thought about my advice to Tab in the other thread ("don't take your wife") before I posted it, because the purpose of his road-trip was to clear his head. That kind of road-trip (in my experience) is typically a pretty solitary endeavor. It might be different for somebody else, but it's true more often than not. When I'm traveling with Jeanie, I'm trying mightily to make sure she's happy. Please be clear-- I like nothing more than being with my wife. But when I'm trying to sort something out on the road, it's not generally productive to make it an "us" thing-- because when I'm with her, my focus shifts to her comfort (as it should) and away from the matter at hand.
Everybody has to find the way that works for them.
