Look, we ALWAYS want it to be good, but sadly, it rarely is... I don't blame it on temporary tracks, just the fact that the machinery has "progressed" (and I use that term very loosely) to the point where the bikes can only be ridden on concrete, and the riders don't have a clue how to ride on dirt because of what the crazy power the bikes have. As I said earlier, if you TRULY attack the track (like Bewley and Holder did), you CAN make it work.
As Crump and Hancock both said, there were a lot worse tracks back in the day - and I can only agree with them...
