This walk is sponsored by the American foundation for the Prevention of Suicide. People walk to raise awareness about suicide. These walks are called "Out of the Darkness Walks." This is the sixth annual walk in Modesto. The Modesto walk has now only raised 40 percent of their goal.
I have taken a couple quotes from their website.
When you walk in the Out of the Darkness Walks, you join the effort with hundreds of thousands of people to raise awareness and funds that allow AFSP to invest in new research, create educational programs, advocate for public policy, and support survivors of suicide loss.
