I wouldn't read into anything too much about where VMX is ATM . The lack of entries for the PC nats is obviously dissapointing for all concerned .
I think it all comes down to $$$$$$$$$$$$$$$ money is tight ATM for most people so recreation and sport are usually the first to slow down.
I used to be able to get across 2 or 3 times a year to race inc the nats and CD but over the last couple of years things have become tight. Our regular visitors from Aus to our events are also feeling the pinch, as Johnny O said VMX is still strong in QLD and Tossa said its all good in WA . Not so much has been said about the other states but you guys would know if there has been a general decline in numbers at local events but i suspect not.
People will have to cut back travelling to the bigger events , its no reflection on the events but just a case of only so may $$$$$$$$$$$$$ to go round.
We have been experiencing a downturn in numbers for the last couple of years (we have been in recession a bit longer than you ) and when you talk to people they are still passionate about VMX but its those $$$ again.
Everything goes in cycles and the economies must come right again sooner or later and when they do i think we will see an upsurge in VMX again .
What you have in Australia is IMHO a bloody good template for all VMX events .
