Well,
I'm 65 and will 66 shortly. I don't do long distance driving anymore. I figure WHY? In most cases, when and where we go, there is plenty of stops/camps/RV parks etc spread out all over this country to try and break long distance driving records. 99.999% of the time, we have no schedule. We go and we stop, when and where we want. If it's a Walmart, so be it. If it's a nice place, we might stay for a couple of days, depending on availability of the spot we're in.
I don't mind driving but, I just don't need to do the marathon thing anymore. There are folks on the Goldwing forum I visit every now and then and some of those boys are nuts. They'll do between 1,000 and 2,500 miles in a weekend. It's called the IRON BUTT club. Heck, I do 150 on the bike and I'm looking for an easy chair.
