These shows are actually getting more popular here. There’s a surprisingly number of people restoring older cars. The climate can be forgiving to cars.
There’s also a lot of interest because 2026 is the centennial of Route 66. Each of the 8 states with parts of the old road, even Kansas with its 13 mile stretch, has a Route 66 Association and each is planning some events. The Springfields, Illinois and Missouri, and Tulsa OK have already planned large car shows and other events. I know of two car groups that have announced plans for driving the current 2,200+ mile route. Even my wife and I are tossing around the idea of doing the route.
