I don't see trials becoming more obscure or dying off. I have seen more articles in mainstream publications and tests of trials bikes in magazines like Dirt Rider than I can remember.
Also, more and more riders are beginning to notice that the top placers in extreme enduros like Ernzberg and Romaniacs are all trials riders. The same is true of the big names in EnduroCross.
However, I think that we can kill the sport if we try to go back to vintage rules.
I'll take a sick nose wheelie any day!!
