As much fun as road trips can be today, it was so much more interesting in the past. Today you can drive a hundred miles, or a thousand, and see exactly the same stores, restaurants, and motels. Maybe this makes it more comfortable for some, but it can also make you suddenly forget where you are because you could be anywhere!
When my wife and I were first married, we began our first "road trip" shortly afterward as I had just received active duty orders. We left NY and headed toward San Antonio, TX for my officer basic training. The Interstate system was only fragmentary, and much of the trip was on two-lane U.S. highways or state highways. Looking for a place to eat, or lodging for the night was a true adventure. Many a time we asked for recommendations from a local gas jockey (no self service gas stations in the mid '60's) and ended up eating at some of the most interesting little Mom-and-Pop diners that I've ever experienced. Motels were a gamble, sometimes being surprisingly nice and sometimes requiring a chair wedged under the doorknob for a sense of security. After San Antonio we went to El Paso, and on our first trip back to NY the following summer we headed straight east across Texas, into LA, MS, and AL before starting north. I still had NY license plates on my little VW, and had the interesting experience of suddenly being surrounded by State Police in Mississippi, and questioned if we were "northern agitators" down in MS to "stir up the xxxxxxx". All in all, road trips were great adventures, if not always the fun kind.
This past spring my wife and I, now married 49 years and counting, took a 7,000 mile road trip through the Southwest and far West and then back to Illinois. Certainly a lot easier with the full Interstate highway system, and certainly not as adventuresome when accessing Trip Advisor on my smartphone while traveling to find a good motel for the next night, but still a great way to travel.
I try my best not to fly anywhere. For all sorts of reasons I still am a big fan of the "road trip".
