Gordo, first let me apologize. I don't like to be a complainer. You as an organizer are the backbone of our sport. So thank you for your efforts. AHRMA organizers all over the country are doing what you do, including the post 79's. It's the right thing to do. we all know it.
My problem is with AHRMA. They take your money but refuse to give you points and Vintage recognition for your bikes. I have tried to get them to include post 79 Twin Shock bikes. I have spoken with the top people there. They refuse to budge and without good reason. They have hurt vintage trials in America. A recent AHRMA trials here had nine riders. There used to be 50+entries.
Again I apologize for being a whiner. I hope your event is a success. Biff is right. Just ride and have fun. If I were closer I would attend.

PS it still bugs me that a 36 year old bike is considered "Post Vintage" by AHRMA.
