This volunteer association was formed as a response to the disgusting incidents of disruptions of military funerals by protestors by motorcycle riders who wanted to pay their respects to the fallen and protect their families, just as those officers and soldiers protected all of us.
The association has the support and involvement of a wide range of local and national motorcycle organziations. They don't ask their participants to hold any political views, just to show respect for the fallen and their families. You'll usually find them lined up near the entrance of the funeral services, standing guard, holding American flags.
Here in the Blogland, these men and women are heroes too.
