To a point you're right; i have no idea about monsta trucks for I thought they just crushed old cars, but there is an over-riding belief among many fans of motor sport that there is more 'fun' to be had in some of the lesser categories you mention. I love tin tops - especially the WTCC - but touring car races can be every bit as processional as many F1 races; the FIA GT championship suffers a similar fate, for no series throws up 100% exciting and exhilirating races. The last FF race I watched had 12 entries, and the radical series is on the whole a bit drab. As for midget cars, are you talkin the true, US style midget cars? If so, that's grass roots motor sport at its finest. But there we have the problem: as I said, if f1 were to die now the TV companies wouldn't be rushing to replace it with any of the above, or any of the many series out there. Just as we see Premiership games and FA cup ties on the TV and not League One clashes or FA Trophy battles, the 'cream' rises to the top, and that cream is determined by big names, star attractions, and the benefit that sponsors get from exposure. F1 has a star draw - Ferrari - which is a bigger name than anything else in motor sport, and star names - Hamilton, Alonso, Raikkonen, Massa, Button - plus Mercedes Benz, McLaren, Williams, et al. The training ground series don;t have that, and that's why they make no appeal to TV bosses. I agree that watching a Formula Three race, or GP2 even, can be more entertaining than many F1 races, but then the opposite is also true. There is, too, a sorry story in the tale of th much vaunted A1GP series, launched a few years ago to fanfare and such as the 'World Series for Motorsport'; it offered great racing, good drivers, and the added cache of country vs country. It's just about dead now. Why? because the TV companies were'nt interested. A sad fact, but true.
