F1 is fantastic. But WRC is hardly 'merely boys with toys'. They may not put as much money into a car, but the teams are just as heavily funded. Not to mention some drivers do both.
Unfortunately, WRC isn't very popular in the US and, because of that sad fact, it isn't aired much. You have to have 'Speed', the channel, to see it. And it's still not on much even on Speed.
That's another thing I used to do. RallyX my Subaru WRX.
