Two problems with long road trips. I developed sleep apnia, which means I've got to have a place to plug in my breather when I stop for the night, and I don't smoke anymore. With most any old MOPAR iron it used to be 6 hours driving munching nuts, drinking Diet Coke and smoking. Stop for gas, pee, buy more coke and smokes and nuts and hit the road for another 6 hours. Some long trips: Georgetown, SC to St. Charles, MO in 20 hours; KC, MO to Laramie to Boise in two days; Reno to Denver in one day; Colorado Springs to Williams, AZ in one day. Now days we do the 740 mile Huntsville, TX to St. Charles, MO run twice a year. We do it right at 13 hours one way. I miss the Ozarks and interstates hypnotize me, so I like to take a more scenic route if I can.
Oh, yeah. Make that three problems with long road trips. The third problem is two boys who always come along with us. Between the two of them fighting constantly and me yellin' all the time, it's a real life zoo wagon rollin' down the highway.
