Racing is almost done in the US?

[jukeboxman]

Maybe instead of saying 'what happened' you could try saying 'how can I revive the interest?'

Take the bull by the horns and see if you can re-kindle the local club and interest in your hobby. Start with posters in your local hobby store, adverts in your local paper.

In similar words from one of your famous Americans, JFK. "Ask not what your hobby can do for you, ask what you can do for your hobby!"
