I agree with most of what you are saying wisey, but I don't want to be the trail building crew, but no one else does it so i help because no one else does... I would love to have the ability to put in what ever i wanted, where ever i wanted it (did u know there are the ability to have DH tracks with over 150 vertical meters)... but everything has to approved by parks Vic, and is directed by trailmix so i just show up on trail days.
I have riden canberra, adelaide and most legal trail sites in Au and Nz, and i agree that the standard of lysterfield trails is not good, but at the moment it seems like the MTB community is happy with them because no one is turning up to trail days... so we are consantly just trying to repair them half arsed (as i dont want to spend all my riding time, on shovels) any time we hassle for new tracks they just say put a reroute here... or do the drainage there.
If there were more people at these trail days it may show to the park Vic guys that there is interest in better tracks.
I would also like to bet that if Youies had the same number of people ride 1 track like they do at lysty it would not fair too well either!!!
I would be stoked if somebody with good trail building experience gave trail mix a call and offered there services to help with the planing and repair of these trails
