Many riders won't be able to attend this protest rally. Some will have to work. Some will be too far away. But that doesa not mean they can't contribute if they feel strongly about the issues facing the motorcycle & scooter community in Victoria.
Take a copy of the flyer to your local newspaper or radio station. Tell a journo how you feel about it. Take a copy to your local MPs office and let the staff know why the protest is happening. See the MP him/her self if you can.
Copy the Flyer and put it up where other riders will see it. Send it out over the internet. Encourage riders who can attend to be there.
