I question a national organization developing and maintaining local tour routes. It seems like local clubs and groups could handle that more nimbly and efficiently and a national cycletouring organization should focus on regional and national routes.
It does solicit and vet information from local people and groups. Personally, I brought about change to its Atlantic Coast route that were helpful due to increasing suburban sprawl in my area. The proposed rerouting came from my experience riding with my local club.
After I posted a trip report on its forum about one of my tours across PA, it contacted me to assist in the development of part of the new Chicago to NYC route.
I have also suggested a few other minor route adjustments here and there based on my experiences. At least one was added to a map addendum. Don’t know if it made it into the next run of printed maps.
I don’t know if it’s still the case, but the website used to have a function where you could submit updates like the closure or addition of services, Don’t know how many people made the effort to do that.
