I think the problem is each sport gets it's own facilities and that gets very expensive and there is a lot less tracks, clubs and generally places to ride like back in the 70's
I have often thought that certain sports could share the same facilities like Aussie Rules, Soccer , Rugby League and Rugby Union could use the same facilities and it would certainly be cheaper. Now my suggestion is that there is a hell of lot of Golf Courses around Australia and some of them have course lighting so the course could be used at night. The answer is obvious to me that golf and VMX would go hand in hand, we can also make the course more challenging for the Golfer.
