It's a shame, the only entities/groups etc, in America that have anything remotely close to incorporating anything Americana is this site, and the United States Sign Council Sign Association.
Oh wait, I don't think there is a USSC anymore, and before I left they removed the Red, White, & Blue out of their logo and tried to chase the coattails of ISA to capture a "international" audience and $$$$$.
However, the USSC involves themselves in more Pro-American causes than ISA, with vets, tributes etc
