Glad you had a great trip. John Wayne's house ... such a small house for such a big man.
I too *road trip* by my lonesome. My two longest solo drives are from Chicago to Billings MT - then down into Yellowstone via Bear Tooth, out through Jackson Hole, then back home. Second longest solo trip was Chicago to Hampton VA (near Norfolk). Lots and lots of solo trips to KY, MI, IN, IA, MO, and OH.
