PPRuNe Forums - Best place to get into serious aerobatics

I am interested in getting into aerobatics quite seriously, and I am planning on moving soon. Which places in the US (or even globally) have a high density and quantity of aerobatics teaching and competition going on?

I am not looking at it just as a hobby, but as something I might do full time.

I read somewhere that Arizona and Florida have a particularly high concentration of flight schools. Would the same be true for learning aerobatics?

I am a slightly older guy, and I have the money to finance it, so that isn't an issue. I am also an international, if that's relevant in any way.

Thank you
