If ACA has strayed from what it once was, you and some friends should consider creating your own organization. Imagine what your ideal organization would do, what services and such you would like to offer.
I don’t live in America, I live in Japan. There are many touring organizations here, and several prefectures in Japan have created their own websites, maps, and such to attract cycle tourists. Routes are figured out and planned, and printed, local businesses, hotels, and such along the routes are solicited to be added to tour brochures for a small fee. Your typical cycle touring brochure is like an old gas station map, showing the route, and places of interest, and small ads for participating businesses.
There are websites and apps in Japan as well, run by the same organizations which print the tour brochures. Brochures are put in stands at train stations, bike shops, and camping outfitters.
An interesting feature some tours have are stamp rallies. Participating businesses or sites keep a rubber stamp which is unique to each location, and cycle tours, hikers, etc stop at each place and stamp their brochures. If you complete all the stamps you can collect a coupon or some silly prize. For some reason these are popular in Japan.
I’ve done a lot of riding around America, all I know of the ACA are their maps.
