PPMD and Run for our Sons Facebook pages say -- "PPMD and Run For Our Sons send prayers to those injured in the horrific bombing at the Boston Marathon. It appears that those running on our behalf and for other Duchenne organizations are safe and accounted for, but we will continue to keep the runners and spectators affected in our thoughts." They also asked that "If you hear anything about anyone from the community, please share information in this post." No one has posted any non-positive information. My son ran the Boston Marathon for RFOS and he and his family are fine.
