As I said earlier (in the other thread, I think), BBB seemed to be structured for the spectators more than the riders - particularly the MX - on the assumption that there would be heaps of both.
Basically, I think it was supposed to run a bit like a country show: At 10:00am, you can see the sheep being displayed, at 10:15am there will be sheep dog trials, and at 11:00am you can come and see the judging of the cattle... And over in the other arena, there's a flower display followed by the trophy presentation for the best jam.
By Sunday this was clearly not working as intended, and the marshals made some judgement calls that deviated from the programme (which were clearly for the benefit of the riders, even though I personally think that throwing the programme out would have been better for everyone). By that time, there were no spectators left - during Sunday's version of Legend Laps, I reckon there were about five times as many 'non-legend' riders waiting to be allowed back on the track, than spectators.
I guess that they'd tried to offer some point(s) of difference from Classic Dirt, but the size of the event does not allow them to work (yet?).
