This Sunday - Blancpain or RX Rallycross?

[cailean]

Not sure which to go to this Sunday, Blancpain Endurance at Silverstone or FIA Rallycross at Lydden Hill? Would like to see both, have never seen either, both about same distance from me.

Want to keep it as family day so 2 young kids and wife with me (they all enjoy motorsport)...

Confused. Any suggestions?

I'm edging towards RX for the fun see it all factor but would like to see the GT racing too. Silverstone is half the price (not that price would be a deciding factor...)
