I've decided I really like state highways. I prefer them to Interstates, US highways, and probably any other kind of long-distance road. Please note that this is no mere passing observation. I have chalked up a great deal of road time this summer, and I have driven on a great many roads. And I must say that state highways are by far the most pleasant. Now, I do have, right now in the back of my mind, a nagging urge to add a qualifier, so I will. State highways are not a pleasant affair if one is in a hurry to get somewhere. But I would venture to say that driving in general is not as pleasant when one is in a hurry. And it is also probably safe to say that when one is in a hurry, one doesn't care about the pleasantness of the drive. Hurrying, I suppose, is a part of life and cannot really be avoided completely. So hurry when you must. However, there is no sense in hurrying through a two or three day road trip. I can't even imagine what it would be like to be continuously in a hurry for two days straight. Conclusion: when you are taking a road trip, opt for the state highways.
In June, while traveling to a reunion, my family and I took "the back way" from Vandalia, Ohio to Logansport, Indiana, avoiding the interstate and using, instead, a number of winding, two-lane highways. It was wonderful! The wheat fields had turned golden already, and the corn was starting to grow, and there were old, old farm houses, red brick and really narrow, and fields of cows, too. Man, I loved it.
Also this summer, I drove from Midland to Austin, which is a long stretch of Texas with pretty much no cities in between. Towns, yes. Cities, no. I think I drove the whole way on Texas highways. And it was great! Who knew west Texas could be so green! Fields covered with a carpet of those cute, scrubby little trees. I also saw signs for some pretty great towns, like Knickerbocker, Salt Gap, Melvin, Hedwigs Hill and Oatmeal. Seriously.
In closing, you are missing out if you always take the interstate. Support your local state highways! :)
