another correction - the lift closes at 4 pm not 6!
and at the top of the track (straight out of the fire road) there are 2 tracks you can take. there is the old one which veers to the left about 5 metres into the single track, it's hard to see if your not looking for it. that track is my favourite, with a few nice jumps, a bridge over a river which is really cool, some little drops leading into tight corners, and some fast sweepig corners. or the new track (new early 2005/very late 2004), that is the track that is raced on (i think this is the one you were talking about).
the track also splits down the bottom at two places, one takes you to Friday flat, this track is mostly fireroad, but it is good fireroad (dirt not gravel) and you can get up to some serious speeds. the other turns off about 4/5ths of the way down and turns nto a almost XC track, about 80% downhill, and lots of fun.
as for pricing, RawNRG are crap. if you live near by or visit regualy you can often swing a season pass for a few hundred.
Cheers,
