I road D-4 observed trails for 2 years and I went to a national event as a spectator and it was total amazing at what these guys can do. If you ever get a chance to go you definitely will not be disappointed. Rapidrobert
There's a trials event website that I found last year, can't remember how. It lists all the events around upstate NY. I planned on attending one or two of them and never did. :-(
I hope to change that this year if I can find that site.
