I love a track day at Crail!
Yeah it's just a few ropey old runways linked up with a crappy surface and zero facilities, but there's few other places where you can have that amount of fun with so little rules.
And add to the fact that its cheap and fairly local, and I'm there as often as I can be
Here's a video a mate made of one of the drift days, which includes some Sierra nonsense too..... (3:05 is quite amusing!)
