Well to be honest, talkin as an EX racer, i wasn't overly impressed for some strange reason i cant put my finger on.
I'm not a fan of the 4 strokes for several reasons, but i think that they are too loud and they all sound the same, it gets a bit much after a while, Bring back 2 strokes asap.
I only went there really to see my old mate Mark Eastwood ride (number 8 in MX1), it was a good day though, and as you say the weather was great.
I didn't know you was into MX!!!
