Yesterday, while out on our Sunday drive to the Best Buy to buy a cable, we found ourselves exiting the freeway slowly behind a lumbering Cadillac driven by a elderly gentlemen who, too, was out on a Sunday drive with his wife.  I turned to my husband and asked, “What will be our Cadillac, seeing as how neither one of us thinks a Cadillac is anything to strive for?”  T’is true, the Cadillac is/was the aim for my grandparents and some of my parents’ older siblings.  But now that is not the automobile aspiration of my parents or myself.   My husband was silent and contemplated it for a minute, and then after a stop light or two we saw a beautiful beast drive by — a vacation on wheels, and together we said, “Oooh, an RV …”  Yes, my husband and I want to the travel around the US in an RV when we retire and 30 – 40-years from now and when we do retire, that RV better drive itself, because I can’t even imagine how much worse my driving could get when I become a senior citizen (anyone who has been in a car with me, knows what I’m talking about …).  Ahh, I can see it now, living in an RV, plugging in waypoints into the navigation computer and waking up in a new place every morning like a cruise ship.  And we can meet up with other land cruisers we’ve met on the Internet and roam the land as one of the many bands of senior land cruisers (Ryans anyone?).  Of course by then, there will be no gas, so it will be fueled by waste or whatever clever fuel alternative emerges victorious from the research that is being done now.  It will be wonderful :).  But you know, if my dream doesn’t come true and my RV doesn’t drive itself within 30-years, then I’m going to be very, very disappointed.
